The recently formed MRAM Alliance SNIA Special Interest Group had a booth at the 2026 SNIA Storage Developers Conference (SDC) where they demonstrated CXL-attached DDR MRAM using Everspin MRAM. MRAM is a non-volatile memory and so it retains data after power loss or a system restart and provides nano-second data access. DDR MRAM complements NAND-based storage, providing 100X faster persistent buffer/cache.

The image below shows the demonstration system which used a Supermicro AS-1116CS-TN server running an AMD EPYC 9355 32-Core Processor with a FPGA demo using and AMD. Alveo U250, full height/length with a Wolley CXL controller and 4 DDR4 DIMMs with 1GB MRAM replacing the DRAM.

The MRAM Alliance exhibit and talks at SDC showed that MRAM has been used in data center storage for more than 15 years and that multiple generations of DDR MRAM have been in mass production for over 10 years with use cases ranging from Journal Memory to Write Data Buffer/Cache. The MRAM demo showed that it can cut XPU idel time and drive AI systems to run at higher utilization with a persistent write cache.

JEDEC sets standards for popular memory modules, such as the various DDR types. There is a new Low Power, LPDDR Persistent Memory (PMEM) activity underway that will enable the use of persistent memory, like MRAM, in standard LPDDR configurations. Allowing persistent memories to work in standard DDR slots will do a lot to make this technology even more useful.

I have been tracking MRAM maker, Everspin ever since they had their IPO in 2016 . This year marks the company’s 10 th anniversary from that IPO. Everspin is the largest and oldest manufacturer of standalone MRAM chips. Let’s look at where the company has come since that IPO.

Everspin reported record quarterly revenue in Q2 2026. Revenue reached $18.7 million, including $15.3 million in MRAM product sales, compared with $13.2 million and $11.1 million, respectively, in Q2 2025. Everspin reported non-GAAP net income of $2.9 million and $43.9 million in cash and cash equivalents on June 30, 2026.

At the time the IPO was announced Everspin was producing 256Mb STT-MRAM and projecting the sampling of 1Gb in 2017. Since that time, Everspin began sampling its 1Gb DDR4 STT-MRAM with lead customers in August 2017, subsequently entered volume production and has been shipping to IBM since then to support sequential generations of Flash Core Modules.

In addition, today the company’s portfolio includes Industrial Grade xSPI STT-MRAM from 4Mb – 256Mb products. Also, it includes high-reliability xSPI STT-MRAM 64Mb – 256 Mb products tested to AEC-Q100 Grade 1. Everspin has also announced NOR Flash-compatible UNISYST MRAM, extending its MRAM roadmap into unified code and data memory. The figure below shows some of the highlights from Everspin’s history (although it doesn’t include the CXL demonstration at the SDC.

Back in 2016 Everspin was expanding its MRAM manufacturing through its relationship with GlobalFoundries. Everspin is further expanding its manufacturing and long-term supply capacity. Everspin entered an initial 10-year manufacturing agreement with Microchip Technology to augment its onshore manufacturing capacity for MRAM and Tunnel Magnetoresistive (TMR) sensor products at a Microchip fabrication facility in Oregon, while continuing to manufacture MRAM and TMR sensor wafers at its Chandler, Arizona facility. The agreement adds wafer capacity and is intended to strengthen long-term supply continuity well into the next decade.

Back in 2016 MRAM was targeted at IoT, automotive/ADAS, consumer devices and vision processing, along with caching, buffering and real-time visual computing applications. Today, Everspin MRAM serves a much broader range of applications, including persistent write buffering, power-loss protection, configuration and boot memory, data logging, SSD caching, RAID controller cards and memory expansion.

Applications span data centers, industrial automation, medical systems, networking and infrastructure, gaming, automotive, aerospace and defense, and other mission-critical systems.

Specific applications include retaining machine state through power interruptions in industrial automation; fast data logging in medical systems; configuration and boot memory in networking infrastructure; transaction logging in casino gaming; automotive engine and inverter control; and data logging and FPGA configuration in low-Earth-orbit satellites.

In addition to the SDC CXL demonstration Everspin recently announced an MOU with MaxLinear to evaluate persistent MRAM for AI-server applications, including metadata management, log data, write buffering and cache functions.

Over its life Everspin has shipped about 200 million units and has 2,000 customers.

MRAM is playing a bigger role in servers with its CXL demonstration at the 2026 SNIA SDC. MRAM was there and it is celebrating 10 years of success since its IPO in 2016.
