Everspin Technologies leads the industry in commercializing the first Spin-Torque Magnetoresistive RAM (ST-MRAM), a new type of high performance and ultra-low latency memory that is expected to transform storage architecture and help drive the continuous evolution of Moore’s Law. ST-MRAM is a performance-optimized Storage Class Memory (SCM) that bridges the role of today’s conventional memory with the demands of tomorrow’s storage systems by providing non-volatility, high endurance and ultra-low latency.

The 64Mb device is the first product in Everspin’s ST-MRAM roadmap that is planned to scale to gigabit density memories with faster speeds. Select customers are now evaluating samples of Everspin’s EMD3D064M 64Mb DDR3 ST-MRAM. “The properties of ST-MRAM are particularly appealing to the enterprise SSD market because of its ability to enhance and complement flash memory technology,” said Joseph Unsworth, research vice president at Gartner. “The commercialization of this technology is an important industry milestone that should continue to drive SSD proliferation in data center and in-memory computing architectures.”

The first semiconductor memory that combines the speed and endurance of DRAM with the non-volatility of Flash, ST-MRAM gives designers of high performance storage systems the ability to achieve ultra low latency, increase reliability with high cycling endurance and protect data in the event of power loss. One example of potential use is in the area of cloud storage—even as more users and content are added, faster and consistent data storage access is a necessity.

“Existing memory technologies face significant challenges to deliver the right balance of performance, power consumption, and reliability as they scale to smaller process geometries,” said Jeff Janukowicz, research director for Solid State Storage and Enabling Technologies at IDC. “The commercialization of the first 64Mb Spin-Torque MRAM is an industry milestone along the path to broader use of more varied non-volatile memory technologies to improve storage device reliability, and to increase performance.”

Everspin’s proprietary Spin-Torque technology uses a spin-polarized current for switching. Data is stored as a magnetic state versus an electronic charge, providing a non-volatile memory bit that does not suffer wear-out or data retention issues associated with Flash technology. The EMD3D064M 64Mb STMRAM is functionally compatible with the industry standard JEDEC specification for the DDR3 interface, which delivers up to 1600 million transfers per second per I/O, translating to memory bandwidth of up to 3.2 GBytes/second at nanosecond class latency. The product is offered in an industry standard WBGA package aligned with the DDR3 standard.

“Data has transcended from being a buzzword to where it’s an invaluable commodity. At the heart of the data revolution is the issue of how to store, manage and retain it securely, efficiently and cost-effectively. Our first ST-MRAM product has the potential to carry today’s high performance storage systems to greater heights,” said Phill LoPresti, president and CEO of Everspin Technologies. “We are collaborating with select customers to allow them to evaluate and take advantage of Spin-Torque MRAM technology sooner and to gather feedback that will help us finalize our 64Mb DDR3 ST-MRAM for production.”

ST-MRAM gives system designers the benefit of persistent, high endurance storage or memory for applications that demand better reliability and that need the performance boost of DDR3 speed. The 64Mb density MRAM provides an ideal entry point for non-volatile buffer and cache memory in solid state and RAID storage systems as well as storage appliances. The 64Mb device will complement existing low cost memory technologies, reducing overall system cost and complexity.

ST-MRAM ecosystem

Everspin is manufacturing ST-MRAM on its 200mm production line in Chandler, Arizona and is collaborating with industry leaders to establish 300mm MRAM tools and additional fab capacity. Everspin is also working with design partners to ensure that the required tools and support are in place to drive the rapid adoption of ST-MRAM, including the necessary memory controllers, memory modules (DIMMs) and evaluation platforms.

Availability

Everspin is shipping working samples of the EMD3D064M 64Mb DDR3 STMRAM to select customers and will announce details on broad availability in 2013. In addition, Everspin is offering ST-MRAM non-volatile random access memory modules in industry standard configurations, and PCIe FPGA platforms are available now allowing customers to start designs. For more information, visit http://everspin.com/spinTorqueMRAM.php
