Everspin Technology

Headquartered in Chandler,Arizona, Everspin Technologies, Inc. is the worldwide leader in designing,manufacturing, and commercially shipping discrete and embedded Magnetoresistive RAM (MRAM) and Spin-Torque MRAM (ST-MRAM) into markets and applications where data persistence and integrity, low latency, and security are paramount. With over 70 Million MRAM and ST-MRAM products deployed in data center, cloud storage, energy, industrial, automotive, and transportation markets, Everspin has built the strongest and fastest growing foundation of MRAM users in the world.

Toggle MRAM Characteristics
NON-VOLATILE Data retention > 20years FAST Symmetrical read/write - 35ns
UNLIMITED ENDURANCE No were-out mechanism MODULAR INTEGRATION Easily integrated with CMOS
EXTENDED TEMPERATURES -40c < T < 150C operation demonstrated HIGHLY RELIABLE Intrinsic reliability exceed 20 year lifetime at 125C

❚ Parallel Interface MRAM

8-bit / 16-bit Parallel Interface MRAM Everspin 8-bit/16-bit Parallel Interface MRAM are SRAM compatible with 35/45ns access timing and unlimited endurance. Data is non-volatile for greater than 20-years. Data is automatically protected on power loss by low-voltage inhibit circuitry to prevent writes with voltage out of specification.

❚ Serial Perripheral Interface

Serial Peripheral Interface Everspin Serial SPI MRAMs are the ideal memory for applications that must store and retrieve data and programs quickly using a minimum number of pins.

Quad Serial Peripheral Interface The MR10Q010 Quad SPI MRAM is the ideal memory solution for applications that must store and retrieve data and programs quickly using a small number of pins, low power, and the space saving 16-pin SOIC package. The four I/O’s in Quad SPI mode allow very fast reads and writes at 52MB per second, making it faster than 8-bit parallel MRAMs. This is great for next generation RAID controllers, server system logs, storage device buffers, and embedded system data and program memory.
