Everspin Technologies has successfully demonstrated the world’s first Compute Express Link (CXL)-connected MRAM platform.
The working demonstration system connects Everspin's PERSYST MRAM to CXL-enabled platforms as persistent memory with memory semantics, combining CXL’s standard high-speed connectivity with MRAM’s ability to retain data without power. Everspin says that CXL-connected MRAM platform creates a fast persistent buffer and cache tier with cache-line-level, nanosecond-class access and writes up to 100x faster than NAND-based solid-state storage.
The demo uses a Supermicro AS-1116CS-TN server with an AMD EPYC 9355 32-core processor, an AMD Alveo U250 FPGA platform with a Wolley CXL controller and Everspin PERSYST 1GB DDR4 MRAM UDIMMs.
Everspin recently announces a partnership with Teledyne HiRel Semiconductors to accelerate MRAM adoption in aerospace and defense applications. In August, the company reported record revenues. In June we posted an interview with Everspin's VP of sales.
