Reliable, Fast, Non-Volatile MRAM for Data Capture and Storage

Everspin Technologies' PERSYST MRAM transforms how industries process, store, secure and manage critical data, offering unmatched speed, resilience, and flexibility.
 
PERSYST includes Everspin Toggle MRAM to provide memory that retains its contents without the need for battery backup or refresh cycles and our xSPI STT-MRAM that provides high data transfer rates with a low pin count and immediate data availability on power-up. The EMxxLX family delivers high performance in a compact pinout and enabling direct drop-in replacement for SRAM and NOR flash.
 
PERSYST MRAM is aimed at applications require instant on data persistence for protection against power loss and system interruptions, unlimited endurance with no performance degradation in extreme environments, and low latency with fast, symmetrical read/write speeds.

A new era for MRAM

PERSYST is setting the standard for performance, efficiency, and scalability across a diverse range of applications.

8" Back End of Line Manufacturing

Through our own US-based manufacturing facility in Chandler, AZ, we can perform BEOL manufacturing on 8" wafers that come from any CMOS foundry, worldwide.  15 years of production, this line is trusted by not only commercial customers but also the US Government.

STT-DDRx

Spin-Transfer Torque DDR MRAM (STT-DDR MRAM) is a high-speed, non-volatile memory that combines the persistence of flash with the performance of DRAM, utilizing a JEDEC-compatible DDR interface.

STT-xSPI

Spin-Transfer Torque xSPI MRAM (STT-xSPI MRAM) is a high-speed, non-volatile memory that combines the persistence of flash with a low-pin-count interface, utilizing a JEDEC-compatible xSPI interface.
