I'll now turn the call over to Luc to provide an overview of the quarter. Luc?

Luc Seraphin - President & Chief Executive Officer

Thank you, Rahul, and good afternoon, everyone. Before we discuss our results for the first quarter, I wanted to take a moment to provide an update on the impact we're seeing from COVID-19. It is clear that we are in unprecedented times, as the industry navigates the uncertainty created by the coronavirus. Our top priority has been the health and safety of our global workforce, customers and partners, and I'm extremely proud and humbled by the collective commitments, patients and ingenuity demonstrated by all Rambus employees in this challenging time.

While we cannot predict the long term with certainty, the current increased demand in our target markets, combined with the strength of our balance sheet, makes me optimistic about the opportunity ahead of us. The Rambus business model is naturally resilient to the near-term financial effects of COVID-19 with a patent licensing business, but is highly predictable due to the long-term nature of our agreements. This provides us financial stability and strong cash generation to weather these turbulent times.

From an operational standpoint, we are on track to deliver on all of our customer commitments. We have been able to maintain a very high level of productivity with product design, development and delivery continuing throughout this transition to a remote work environment.

Finally, the almost universal shift to learning and working from home has placed a tremendous strain on the global data infrastructure in terms of increased bandwidth, capacity and security. These increasing requirements for faster and safer hardware are accelerating demand for Rambus IP and chips in the data center, cloud and 5G. As a result, the number of design starts and customer demand for IP and chips remained strong, reaching some tailwinds for the business. The Company's focus on our core strength in semiconductor, emphasis on operational efficiency and strong cash generation have built an enduring foundation for growth even in this challenging environment.

Turning now to our results. This combination of factors, coupled with our continued execution, has translated into an exceptional first quarter. We delivered $64 million in revenue, exceeding the high end of expectations and outstanding cash generation from operations of $37.3 million, further strengthening our balance sheet. The licensing team continues to make great progress as highlighted by last week's announcement of our DRAM patent license agreement with CXMT. This agreement is a great demonstration of the ongoing relevance of our portfolio as the term extends well beyond our existing agreements. While the near-term impact of the deal on revenue will be small due to how nascent the DRAM market is in China, we are optimistic about the potential long-term impact as the market grows.

Our product team had a tremendous performance with record revenue from both silicon IP and chip businesses. The silicon IP business delivered record revenue in the first quarter, augmented by multiple tier-1 SoC design wins and strong execution from last year's acquisitions. We introduced three industry-leading products to deliver and protect data. The 112-gig XSR chiplet interface, an HBM2E memory solution with integrated PHY and controller, and 800-gig MACsec security IP solution. This strengthens our position in the fast-growing and critical markets of data center, cloud, AI and 5G with additions to both the high-speed interface and security IP portfolios.

Memory interface chips continue to be the fastest-growing segment of the business, delivering its fourth consecutive quarter of record revenue. The growth was driven by ongoing gains in market share and was bolstered by the increased demand for memory in data center and cloud that is being echoed by other players in the industry. Our emphasizing excellence in quality and delivery, data center and OEM qualifications continue to increase for the DDR4 memory interface chipset, and the Company remains well positioned as a first mover for the industry transition to DDR5.

In closing, COVID-19 has introduced a great deal of uncertainty into the market, but the global shift to increase remote collaboration has also presented us with an opportunity for upside. The resilience of our business model, ongoing ability to execute and increased demand for our products across the critical markets of data center, communications, AI and 5G give us confidence in our ongoing ability to generate cash, further strengthen our balance sheet and reinvest in our future. Our innovations and products are well aligned to near and long-term customer demand, giving us the stability and flexibility to position ourselves for success throughout the rest of the year and beyond.

With that, I'll turn the call to Rahul to discuss the quarterly financial results. Rahul?

Rahul Mathur - Senior Vice President & Chief Financial Officer

Thanks, Luc. I'd like to begin with our financial results for the first quarter. Let me start with some highlights on Slide 6. As Luc mentioned, we continued to execute in our product businesses and delivered excellent financial results above the high end of our revenue and earnings expectations, while continuing to strengthen our balance sheet. We've adopted ASC 606 using the modified retrospective method, which does not restate prior periods, but rather runs the cumulative effect of the adoption through retained earnings as a beginning balance sheet adjustment. Any comparison between our results under ASC 606 and prior results under ASC 605 is not accurate way to track the Company's progress. We will continue to provide operational metrics such as licensing billings to give our investors better insight into our operational performance.

We delivered revenue of $64 million and licensing billings of $67.1 million. Revenue was higher than our expectations, due to strong buffer chip sales. We have a very strong balance sheet and ended the quarter with cash, cash equivalents and marketable securities of $435.4 million, up from the previous quarter due to cash from operations of $37.3 million. Our continued execution on our strategy and our operational discipline has yielded excellent financial results and a strong balance sheet that affords us flexibility on our strategic initiatives.

Now, let me walk you through some revenue details on Slide 7. Revenue for the first quarter was $64 million, well above the high end of our expected range due to market share gains in our buffer chip business. Royalty revenue for the first quarter was $19.7 million, while licensing billings were $67.1 million. The difference between licensing billings and royalty revenue primarily relates to timing, as we don't always recognize revenue the same quarter we bill our customers. Going into additional detail, our product revenue was $30.7 million, consisting primarily of our buffer chip business. Our contract and other revenue was $13.6 million, consisting primarily of our silicon IP business. As a reminder, in Q4, we recorded $0.9 million of revenue associated with our Payments and Ticketing business prior to the sale to Visa. So this reflects record results in Q1 for both buffer chip and silicon IP. Our growth in these areas illustrates the benefit of our focus and strategy.

Let me walk you through our non-GAAP income statement on Slide 8. Along with our excellent revenue performance in Q1, we also exceeded our profitability targets. Total operating expenses, including COGS, for the quarter came in at $63.5 million. Operating expenses of $51.9 million were lower than our expectations due to lower spending on employee-related expenses such as travel. With higher revenue and disciplined execution on spending, our profit was nicely above our expectations. We ended the quarter with headcount of 665, down from 685 in the previous quarter, primarily due to attrition.

Under ASC 606, we recorded $4.4 million of interest income related to the financing component of our fixed fee licensing arrangements, for which we have recognized revenue, but not yet received payment. We incurred $0.6 million of interest expense related to the convertible notes we issued in Q4 2017. This was offset by incremental interest income related to the return on our cash portfolio. After adjusting for non-cash interest expense on our convertible notes, this resulted in non-GAAP interest and other income for the first quarter of $5.6 million. Excluding the interest income related to the significant financing component of ASC 606, this would have been $1.2 million. Using an assumed flat rate of 24% for non-GAAP pretax income, non-GAAP net income for the quarter was $4.7 million.

Now, let me turn to the balance sheet details on Slide 9. Over the past several years, we have built a very strong balance sheet. Cash, cash equivalents and marketable securities totaled $435.4 million, up significantly from the previous quarter primarily through cash of operations - cash from operations of $37.3 million. At the end of Q1, we had contract assets worth $487 million, which reflects the net present value of unbilled AR related to licensing arrangements, for which the Company has no future performance obligations. I expect this number to continue to trend down as we bill and collect for these contracts. It's important to note that this metric doesn't represent the entire value of our existing licensing agreement that several customers have royalty-based agreements that allow us to recognize revenue each quarter under ASC 606.

First quarter capex was $4.5 million and depreciation was $4.8 million. We delivered $32.8 million of free cash flow in the quarter. Looking forward, assuming construction is resumed, I expect roughly $12 million of capex for the second quarter and roughly $23 million for the full year of 2020, half of which is related to the relocation of our headquarters facility. I also expect depreciation of roughly $5 million for the second quarter and roughly $20 million for the full year of 2020. Our strategic refocus on our core markets and operational efficiencies have set a solid foundation for our Company. Our limited debt and predictable high-margin licensing business have put us in a position to come out of the current environment stronger than ever. We continue to build cash and have limited debt. Due to the predictability of our licensing agreements, we expect to maintain our ability to generate solid cash from operations in 2020.

With a disciplined financial approach that has built capital while investing in growth, we have the liquidity to weather any sustained weakness and are well positioned to take advantage of any uncertainty in the market, both organically and inorganically. Furthermore, our historical and ongoing investments in technology R&D have helped us build a patent portfolio that is foundational to our industry and positions us well for our licensing renewals in the upcoming period. Our recent license with CXMT demonstrates that the ongoing and long-term relevance of our portfolio extends well beyond the length of our current agreements. Long term, we are optimistic about the licensing opportunities in China that we don't expect significant financial benefit from this royalty-bearing agreement in the near term.

Now, let me turn to our guidance for the second quarter on Slide 10. As a reminder, our forward-looking guidance reflects our current best estimates, and our actual results could differ materially from what I'm about to review. In addition to financial outlook under ASC 606, we've also been providing information on licensing billings, which is an operational metric that reflects amounts invoiced to our licensing customers during the period adjusted for certain differences. As you can see in the supplemental information we provided on Slide 14 of our earnings deck, licensing billings course - closely correlates with what we had historically reported as royalty revenue under ASC 605. As Luc mentioned, we saw tailwinds in the form of increased demand in data center and infrastructure and had a fantastic first quarter. While we are optimistic about the potential for these trends to continue, we are remaining conservative in our guidance for Q2, due to the lack of visibility and uncertainty created by COVID-19 and as we continue to monitor inventory status in the industry and supply chain.

With that said, under ASC 606, we expect revenue in the second quarter between $50 million and $56 million. We expect royalty revenue between $9 million and $15 million. We also expect licensing billings between $57 million and $63 million. We expect Q2 non-GAAP total operating expenses, which includes COGS, to be between $62 million and $66 million. Under ASC 606, non-GAAP operating results for the second quarter are expected to be between a loss of $5 million and $15 million. For non-GAAP interest and other income and expense, which excludes interest income related to ASC 606, we would have expected $1 million in income, which includes $0.6 million of interest expense related to the notes due in 2023. Based on the tax legislation passed at the end of 2017, we expect our pro forma tax rate in 2020 to remain consistent with our 2019 pro forma tax rate of roughly 24%. The 24% is higher than the new statutory rate of 21%, primarily due to higher tax rates in our foreign jurisdictions. As a reminder, we pay roughly $20 million of cash taxes each year, driven primarily by our licensing agreements with our partners in Korea.

We expect non-GAAP taxes to be between a benefit of $1 million and $3 million in Q2. We expect our Q2 share count to be roughly 116 million basic and diluted shares outstanding. This leads you to be between a non-GAAP loss per share of $0.03 and $0.09 for the quarter.

I'd like to provide some additional context as to how we developed our guidance for the quarter. We are fortunate to have a strong base of predictable recurring patent license agreements, and our guidance reflects some of the structural step-downs we've discussed previously. In our product businesses, we continue to be actively engaged with our partners on chip design activity and have backlog that represents approximately 80% of our expected chip and silicon IP revenue for the quarter. Our Q2 guidance, therefore, reflects a combination of our structural step-downs and conservatism in an uncertain environment. We continue to manage cost carefully and invest in our R&D programs. The travel and other activities are limited. While we have reasonable visibility for Q2 and are encouraged by the engagement with our partners, given the uncertainty surrounding the global macroeconomic environment with COVID-19, we don't yet understand how our end-markets will be impacted in the second half of this year. While we don't provide guidance beyond Q2 and demand remains robust due to the resilience of our model even if Q3 and Q4 were 10% lower on the top line than what we expected in January, I expect the same overall profitability for the year, due to our strong performance in the first half.

Let me finish with a summary on Slide 11. We are proud of the excellent performance by our team and the progress we continue to make against our strategic initiatives to drive long-term profitable growth. While we understand that ASC 606 added a level of complexity to our financial reporting, it's important to reiterate that the underlying financial strength of our business remains strong reflected in our demonstrated ability to generate cash. We have refocused our product portfolio around Rambus' core strength in the semiconductor industry, improved our operational efficiency and profitability, generated solid cash from operations and leveraged our balance sheet to support our strategic initiatives. We continue to focus on our core markets and are well positioned to come out of the current environment stronger than ever.

Before I open up the call to Q&A, I would once again like to thank our employees, customers and partners. Everyone, please stay safe and take care of yourself and your families. Your health is more important than anything will discuss on our call today.

With that, I'll turn the call back to our operator to bring Q&A. Could we please have our first question?

Question & Answers

Operator

Thank you, Rahul. [Operator Instructions] Your first question comes from the line of Suji Desilva with ROTH. You may now ask your question. Suji, your line is now open. You may now ask your question.

Suji Desilva - ROTH Capital Partners - Analyst

I'm sorry about that. Luc, Rahul, thanks for the well wishes from you guys and hopefully Rambus family is doing well as well.

Luc Seraphin - President & Chief Executive Officer

Thank you, Suji.

Suji Desilva - ROTH Capital Partners - Analyst

So on the guidance, Rahul, if I take your numbers and try to adjust to what I would think the non-GAAP is, I get to 1Q results actuals of $111.4 million and EPS of $0.32. Is that about where those numbers will fall out?

Rahul Mathur - Senior Vice President & Chief Financial Officer

So Suji, I think what you're doing is you're substituting licensing billings for what we normally report as royalty revenue.

Suji Desilva - ROTH Capital Partners - Analyst

Correct.

Rahul Mathur - Senior Vice President & Chief Financial Officer

And obviously, that's not GAAP and those aren't numbers that we can provide, but if I were to do the math and I get the same math that you did for Q1.

Suji Desilva - ROTH Capital Partners - Analyst

Okay. Just to make sure I cover this all. The guidance seems to be leading to something closer to $101 million and $0.25. I want to make sure that also sounds reasonable.

Rahul Mathur - Senior Vice President & Chief Financial Officer

Yeah. On the same basis, I think what you're doing is you're replacing our guidance for royalty revenue with licensing billings. And if I were to do the same math, yes, I get the same numbers.

Suji Desilva - ROTH Capital Partners - Analyst

Okay. I appreciate that. And then, on the business itself, the memory buffer, I don't know if you've guided the full year or not. If you did, I missed it, what it might be in 2020. I know the visibility is lower, but can you talk about the linearity here? Are you depending on cloud spending? It's been stronger near term and I expect to continue to take a pause for digestion. Any color there would be helpful.

Luc Seraphin - President & Chief Executive Officer

Yeah. Hi, Suji. This is Luc. Yeah, we had a great quarter in the first quarter for our buffer chip business. Our product revenue was $30.7 million in the first quarter, which was much higher than the same quarter a year ago. So we see continued gains in market share on our side, and we see demand going up at least in Q1 and Q2 for server memories and that's as you said, due to the increasing demand for work-from-home and learn-from-home environments. So we did see an uptick and increased market share on our side. So - that led us to very good results in Q1. We are very optimistic about Q2 in the numbers that Rahul just shared with you.

And in the long run, we continue to see high demand for data centers type of memory modules. Of course, with the uncertainty of COVID-19, Q3 and Q4 may be a bit turbulent given the possible impact on supply chain, but we remain confident with our business going forward for Q2 and in the long run.

Suji Desilva - ROTH Capital Partners - Analyst

Okay, I appreciate that color. And then, maybe more broadly, that's one example of what's happening with the COVID, the remote work, learn straining the infrastructure and being something of a benefit for your business like [Phonetic] for better term. Can you talk about other qualitative examples? You talked about the cores and things like that. Just any color anecdotally would be helpful.

Luc Seraphin - President & Chief Executive Officer

I think some markets will resist better than others to the COVID-19 crisis. Everything that has to do with building infrastructure will be more resilient than markets in the automotive space or consumer space for example. And a lot of our IP - the above and beyond our chip business, a lot of our IP actually goes into infrastructure chip development for 5G or AI. So high-speed interface designs with our customers continue to be very relevant. Our security business continues to be very relevant as well. And as you noticed, we announced three new products this quarter that will strengthen our position in those markets. This was 112-gig XSR PHY and controller - HBM2 controller and the 800-gig MACsec in the security space.

So all of these markets are going to resist better than others, and we do develop IP that goes into chips that serve those markets. And again, Q3, Q4 may be a bit turbulent, but in the long run, both our products and our end-markets are going to be more resilient to the crisis than other products and other markets.

Suji Desilva - ROTH Capital Partners - Analyst

Okay. And then, one last quick question on the new China DRAM agreement if you can provide the color. Historically, with Samsung, hynix and Micron, you had to kind of go back to kind of more flattish licensing structure than variable on average. With this new customer given the geography and the opportunity for upside in DRAM, if they can gain share, did you negotiate a variable component here that would benefit you, or did you not - were you not able to? Can you discuss that?

Rahul Mathur - Senior Vice President & Chief Financial Officer

Hey, Suji. It's Rahul. As I mentioned in prepared remarks, this is a royalty bearing agreement. So as CXMT continues to grow and then I'd expect to see our billings from CXMT continue to increase as well. As I mentioned in the prepared remarks, there is still going to be a relatively small portion of the industry on the near term, but we are very optimistic about the licensing opportunity in China over the long term. And as I mentioned earlier, what this also does is it gives us a lot of confidence because it's essentially an independent third-party validation about the strength of our licensing portfolio well beyond the existing renewals and extensions in our current contracts with the other large DRAM providers.

Suji Desilva - ROTH Capital Partners - Analyst

Absolutely. All right. Thanks. I appreciate the color, guys.

Luc Seraphin - President & Chief Executive Officer

Thanks, Suji.

Rahul Mathur - Senior Vice President & Chief Financial Officer

Thank you.

Your next question comes from the line of Sidney Ho with Deutsche Bank. You may now ask your question.

Jeffrey Rand - Deutsche Bank - Analyst

Hi, this is Jeff on for Ho. Congrats on the good results in the tough market environment. Can you talk a little bit about what the biggest headwinds you're seeing from COVID, and has there been any changes in our customer behavior?

Rahul Mathur - Senior Vice President & Chief Financial Officer

Hi, Jeff. It's Rahul. Thanks for your question. So I think from a headwind perspective, it's been interesting because we've seen a pretty robust business across the board. As we mentioned, we reported record results both in our chip business as well as our silicon IP business because of the strength that we see in data center and some of the other key markets. We've continued to see a fairly robust design activity cycle through our silicon IP business, so that's been strong as well. I think if we have seen any weakness that's been in any of our businesses, which have more of a short-term sales cycle, so you could see that in some of our silicon IP businesses in the coming quarter, and I think that's reflected a bit in our guide for Q2. Did I help answer your question?

Jeffrey Rand - Deutsche Bank - Analyst

Yeah. It sounds great. Thank you. And just as a follow-up, can you give us a ballpark of how much of your revenue is generally fixed [Phonetic] to go with the environment and how much could be more variable?

Rahul Mathur - Senior Vice President & Chief Financial Officer

So between fixed and variable, I think one way to look at it is that we ended the quarter with about $487 million on our balance sheet regarding the unbilled contract assets. And one way to look at it again, if you look at our press release what we reported from a royalty revenue perspective was about $19.7 million. So that's royalties under ASC 606 where there is a performance obligation. So for example, it's related to shipment. What we reported in licensing billings on the other hand was about $67.1 million. So that includes any agreements where there's no performance obligation. So if you look at the difference there between $67.1 million and $19.7 million, I don't mean it to put you through a quiz, but that difference is about $45 million. So $45 million - $47 million a quarter at least in Q1 was the difference there, which you could attribute to agreements where there is no performance obligation where it's just billing and collecting.

Now, as I mentioned in our Analyst Day in September, we have given a range of licensing billings from the $220 million to $240 million range, so about $230 million for the year. So that kind of gives you an idea of where we expected the year to come out at least in September, and I think the other numbers also give you an idea of how much is you would call fixed versus variable. Is that helpful?

Jeffrey Rand - Deutsche Bank - Analyst

Yeah. Great. Thank you very much.

Rahul Mathur - Senior Vice President & Chief Financial Officer

You're most welcome.

Your next question comes from the line of Gary Mobley with Wells Fargo. You may now ask your question.

Gary Mobley - Wells Fargo - Analyst

Hey, guys. Let me extend my congratulations on a strong start to 2020 given the circumstances. I wanted to ask about perhaps what you didn't say so far on the call and that is some reiteration of your buffer chip sales. I think the guidance midpoint previously for 2020 was $90 million and $400 million in overall revenue. Are you hesitant to sort of reaffirm that number or raise it higher simply because you're worried about some of the data center guys pulling forward capacity or some inventory out there of dual in memory modules?

Rahul Mathur - Senior Vice President & Chief Financial Officer

Hey, Gary. Thank you very much for your comments, and it's a great question. As I mentioned, our guide for Q2 reflects a combination of some of the structural step-downs we have in our licensing agreements as well as a bit of conservatism just based on everything we see and read externally from macro environment. The demand from our partners continues to be very robust. So I think the cautiousness that that you heard when I talked about the second half is really just that is, that I think we're an environment where you have less visibility. And as I mentioned in the prepared remarks, we do look at what the inventory looks like both in the supply chain and across the industry. And so, that kind of also helps us frame how we look at the second half. So let me be clear, everything that we are getting from our customers is very positive.

Gary Mobley - Wells Fargo - Analyst

Okay. I wanted to touch base on the CXMT license agreement and in to the extent you're willing to talk on behalf of each party involved in this license agreement, I was curious to know whether this relates to their desire for domestic consumption for DRAM or if this was driven largely by their desire to move outside of the China market.

Luc Seraphin - President & Chief Executive Officer

Yeah. Hi, Gary. This is Luc. It's actually both. I think everyone investing in DRAM technology has so large investments to see that they have to address the global markets. And therefore, they need to be able to address their domestic market probably first and then the global markets. But the important aspect of this agreement is twofold. One is that it's a royalty-bearing agreement. And so, although we expect revenue to be low at the beginning, because these technologies take time to mature and ramp in production. When it goes into production, our royalty stream is going to be growing with their revenue. And the second thing is that it shows the strength of our patent portfolio because the terms of this agreement extend well beyond the terms of the current agreements we have with DRAM vendors. So strategically, that's an important step for us to have that agreement with CXMT.

Gary Mobley - Wells Fargo - Analyst

Okay. On the idea of patent strength, I'm curious if you could address the topic of one of your big three patent licensees coming up for renewal this year and sort of the prospects of getting that across the goal line.

Rahul Mathur - Senior Vice President & Chief Financial Officer

Hi, it's Rahul. I'll tell you, we are very confident that we have a renewal with Micron. I think that's coming up in the fourth quarter. And we're very confident that they will renew for a bunch of reasons. One is that if you look at the terms of that agreement, Micron is substantially larger than they were when we signed into that agreement about five, six years ago. And so, it just wouldn't make sense for them to necessarily come back to do some sort of renegotiation. And we think it's a pretty attractive license and then after that, you would have Samsung coming up for a renewal in the 2023 and then hynix in 2024. So we have fairly good visibility between the DRAM industry on a typical year.

And of course, Gary, as we've talked about, sometimes there is ups and downs, but on a typical year, we had about $150 million a year from our DRAM industry. I think one thing that you look at is that our patent portfolio continues to grow. I think we are now at 2,900 plus patents and application. I mean, that's part of our worldwide portfolio, which includes patents in multiple jurisdictions. And as you were talking to Luc about earlier, the license that we have with CXMT is actually a patent license to our worldwide portfolio, not just China. So we continue to file and we have new relevant patents that continue to be issued. And I think that's important as well, but we are very confident about the future of our licensing business in the long term.

Gary Mobley - Wells Fargo - Analyst

That's it. All right. Thank you guys. Again congrats.

Rahul Mathur - Senior Vice President & Chief Financial Officer

Thank you, Gary.

Luc Seraphin - President & Chief Executive Officer

Your next question comes from the line of Mark Lipacis with Jefferies. You may now ask your question.

Mark Lipacis - Jefferies - Analyst

Hi, thanks for taking my questions. Could you review a bit on the product side, like how your supply chain is set up like where the major centers for packaging and testing. One of the things that we heard is that as this virus has spread from China to Malaysia and the Philippines that there is also issues in the supply chain there. And I was wondering if you could just give us some framework for thinking about where you guys where the major operations are centered, have you encountered any issues you anticipate, does your guidance anticipate any supply chain disruptions on the product side? That's the first question. I had a follow-up.

Luc Seraphin - President & Chief Executive Officer

Yeah. Hi, Mark. This is Luc. That's a great question. As we said earlier, we had a record quarter in Q1. One of the reasons we had a record quarter is that we could continue to ship in high volumes and upsize to our customers. And one of the reasons is that our supply chain had been quite resilient. We - our supply chain is mainly located in Taiwan and Korea. So all of the issues that were impacting Malaysia and Philippines, we've been kid of immune to those. And that allowed us to continue to ship without any issues.

And as - over the last four quarters, we continued to gain market share. We've also built a resilient supply chain by building some strategic buffer of stock, if you wish, in critical places of our supply chain, so that we could serve the upsurge of demand, which has happened during this crisis. So again, I think our supply chain is based in countries that have been very literally impacted Korea and Taiwan. And we had built some strategic inventory across the supply chain to deal with upsurge in demand, so that put us in a very strong position for Q1 and for Q2 as well.

Mark Lipacis - Jefferies - Analyst

That's very helpful. Also other - the second question I had was, Luc, you used the expression potential for turbulence in the second half of the year and I think everybody is extremely empathetic to that idea, sometimes the turbulence is a broad expression. It could be issues on the demand side or on the supply side, is there - is - when you talk about turbulence, is there also embedded in that an idea that there is a potential that because demand was so high that there may have been double ordering or pulling quarters ahead into the first half of the year. From the second half of the year, is there any way that you guys can determine that if you even have suspected that, that was the case.

Luc Seraphin - President & Chief Executive Officer

That's a great question, Mark. I think when I talk about turbulence, let me explain what I meant. I think the whole supply chain ordered a little more than they would usually do as an insurance policy because supply chains are very complex and anything that breaks in the supply chain can impact the rest of the supply chain. And it's not necessarily the chips themselves or the materials that goes on the modules. It can be a gas that the factory needs to have to manufacture their products. I think the whole supply chain inbound and outbound have been a bit prudent, and I've ordered a little more than they would usually do, but we don't see situations at this point in time where we see double bookings or overhauling of chips. That's not the case for the time being.

What we see is a combination of higher demand in the short run, because of the work-from-home and learn-from-home environment. And at the same time, the whole supply chain taking a kind of insurance policy by building a little more than they - would they usually do in order to protect themselves against potential incidents in the supply chain. And that's why Rahul was talking about Q3, Q4 saying that we are optimistic but at the same time, we are prudent about what we got. Rahul, you want to add something?

Rahul Mathur - Senior Vice President & Chief Financial Officer

[Speech Overlap]. Yeah.

Mark Lipacis - Jefferies - Analyst

That's great. May I ask just one last follow-up?

Luc Seraphin - President & Chief Executive Officer

Of course, sure.

Mark Lipacis - Jefferies - Analyst

Yeah, so last week, the Department of Commerce announced some additional restrictions on sales to China, Russia and Venezuela I believe associated with military and markets, applications and having to do with civilian exemptions. Can you share - I assume that you guys had - has a chance to review that at least on a preliminary basis. Can you share with us your views on how that might impact Rambus?

Luc Seraphin - President & Chief Executive Officer

Yeah. We continue to monitor those rules and restrictions very, very closely and make sure that we comply to them. Our business is not exposed to those as we understand today, but we will continue to monitor the situation. In the case of CXMT, this is a kind of the opposite situation where our DRAM partner in China is actually paying us for patents, not for technology, so they're paying us for the rights to actually develop their own products, including our ideas. So we're not exporting anything. We're just giving them the right to use inventions that we intended ourselves.

Mark Lipacis - Jefferies - Analyst

Got you. That's very helpful. Thank you very much.

Luc Seraphin - President & Chief Executive Officer

Thank you, Mark.
