Thank you, Leanne, and good afternoon, everyone. I'm pleased to report a solid year for Everspin in which our revenue grew over 32%, and gross margins improved by 550 basis points. Throughout the year, we achieved sequential quarterly revenue growth, setting records each quarter driven by the strong growth of sales in our Toggle MRAM products business.
We exited the year with a total backlog of $13.7 million compared to $7.4 million at the end of 2016, reflecting increased demand for our products. In addition to the strong financial performance during our first full year as a public company, we also achieved shipments of the industry's first commercially available Spin-Transfer Torque, or STT-MRAM product, using our proprietary perpendicular magnetic tunnel junction or pMTJ technology.
Since my start as CEO in September, we've taken a number of steps to evolve the company from a developer of innovative MRAM technology into a company focused on market development that targets new market applications and focuses on value propositions to attract new customers. To that end, we have invested a significant amount of resources in both product and ecosystem development to be well positioned for the ramp of our STT-MRAM products in 2018 and beyond.
In addition to these efforts, we are implementing operational excellence initiatives to build scale, improve manufacturing efficiencies and reduce costs in order to maintain our leadership and competitive advantage in the MRAM market.
Turning first to some operational updates. Our Toggle MRAM business is performing well and we are pleased with the sustained value that these products deliver to our customers. For the full year 2017, we grew our Toggle revenue 27% over 2016, achieving sequential growth every quarter throughout the year. Additionally, our gross margins continue to be very solid for these products and they increased significantly compared to the prior year. We have a healthy pipeline of Toggle MRAM design wins with notable gains in both the industrial and automotive markets. We believe our market share expansion initiatives have positioned us well to deliver on our expectations for solid Toggle revenue growth in 2018.
Now let me provide an update on some important developments since our last call. First, the previously discussed reprioritization of our 256 megabit product as the primary STT-MRAM production vehicle for our customers is going well. I'm pleased to report that in the fourth quarter, we reached a significant milestone and recorded our first revenue for our 40-nanometer 256 megabit STT-MRAM product, entering the process of ramping production volume. This is a notable achievement making Everspin the first company to reach volume production of an STT-MRAM pMTJ technology. This achievement also marks an important turning point in our partnership with GLOBALFOUNDRIES evolving from strictly joint development activity into a mass production relationship where we've actively engaged with our operations team on driving the production ramp.
On the customer side, the previously communicated milestones of SMART Modular Technologies completing their NVMe storage accelerator product qualification in the first quarter, and our lead flash array customer completing their qual in the second quarter, remain on track.
Next, I'd like to provide an update on our progress on the developments of our 1-gigabit STT-MRAM product. On the last call, I stated that we would come back after reviewing data points collected in the fourth quarter and then provide an update on the status of the program. As we communicated recently in our published investor decks, we expect to provide customer samples by the end of 2018 and plan to subsequently ramp production in 2019. We believe this higher-density component will allow us to expand into new applications while also bringing lower cost per bit benefits to our customers.
As to our embedded MRAM activities, our joint technology development with GLOBALFOUNDRIES continues to progress. In late February, Jeff announced the development of an ultra-low power MCU reference design that will use eMRAM technology jointly developed by GF and Everspin. This expands the eMRAM offerings on the 22-nanometer FDX platform and will enable applications such as battery powered IoT products, consumer and industrial microcontrollers as well as automotive controllers. We are pleased with this progress and believe it will have a positive impact on the royalties Everspin will see in future years from eMRAM at GF.
In marketing our technology and products, Everspin and SMART Modular Technology jointly participated in January at the SNIA Persistent Memory Summit in San Jose, where we demonstrated the performance benefits of our persistent STT-MRAM technology, as well as smart storage accelerator that uses Everspin nvNITRO technology.
Earlier this month, we also were at the embedded world trade show in Nuremberg, Germany, engaging several customers predominantly around our Toggle MRAM products. We were pleased by the increasing interest in developing use cases for our high-density STT-MRAM as well as the continued strong interest from new and existing customers in our Toggle MRAM technology.
Beyond operations and products, we have taken steps to strengthen our balance sheet. In early February of this year, we successfully completed a secondary offering, raising an amount of $24.5 million net of underwriter fees. This new capital will give us the runway to drive the company towards profitability while providing us the working capital necessary to ramp our new technology and continue to invest in R&D for our future product roadmap.
Additionally, we continue to invest in our IP portfolio through the filing of patents. In 2017, we had 64 new patents granted, which is our second highest in recent history. This builds upon a patent portfolio already strong in MRAM patents as well as other magnetic circuit innovation. We have several activities in progress to capture value from these assets, with the potential to generate additional sources of cash for the company. We are hopeful that we will see some short-term realization of some of these efforts.
In summary, I believe we are in a unique position as the only company supplying MRAM products to the market today, and Everspin will benefit financially in 2 ways through the sales of our discrete MRAM products and as future royalties from embedded MRAM shipments. We offer customers a compelling value proposition of high performance and endurance in a persistent memory that separates MRAM from other memory technologies such as SRAM, DRAM, flash and storage class memories.
As we look forward to the coming year, we are focused on 3 key areas to drive revenue and profitability while extending our leadership in MRAM technology. First, improving the performance of our Toggle MRAM product business to grow revenues and increase profits; second, delivering the value proposition of our Spin-Transfer Torque MRAM products to key target markets and promoting adoption as we ramp volume production of our 256 megabit device. In parallel, we are driving the development of our next-generation 1-gigabit STT-MRAM product to completion; and third, continuing investment in the development of new products and technologies for the future.
With that, I'd now like to turn the call over to Jeff Winzeler, our CFO, who will review the financial details of our fourth quarter and full year results as well as provide our first quarter 2018 guidance.
