What is billed as the highest performing persistent memory available, magnetoresistive random access memory (MRAM), is now available commercially from Everspin Technologies Inc.

The STT-MRAM product family, called EMxxLX, can be used for data persistence and integrity, low power, low latency and security in electronic systems. This includes applications such as:

  • Industrial internet of things (IIoT)
  • Network and enterprise infrastructure
  • Process automation and control
  • Aeronautics/avionics
  • Medical
  • Gaming
  • Field programmable gate arrays (FPGAs)

Everspin said the STT-MRAM features a full read and write bandwidth of 400 megabytes per second via eight I/O signals with a clock frequency of 200 MHz. The devices are offered in densities from 8 to 64 megabits and are designed to be an alternative to SRAM, BBSRAM, FRAM, NVSRAM and NOR flash devices.

Additionally, MRAM technology is less susceptible to the effects of radiation than other persistent memories. The MRAM products are already in use by aerospace vendor Airbus in some of its critical aviation systems.

“Our EMxxLX MRAM devices offer SRAM-like performance with low latency, maintain memory without requiring power, and have extremely high endurance,” said Sanjee Aggarwal, president and CEO of Everspin Technologies. “Additionally, they are compatible with other memory types and easy to design in.”
