Everspin announces a new 128Mbit xSPI STT-MRAM product

A few months ago, Everspin Technologies launched a new family of SPI/QSPI/xSPI interface MRAM products that offer the world's highest performance persistent memory with full read and write bandwidth of 400 Megabytes per second through the new JEDEC expanded Serial Peripheral Interface (xSPI) standard interface. The EMxxLX family was launched with densities ranging from 8 Mbit to 64 Mbit.

Today Everspin announced a new xSPI MRAM device, the EM128LX, that expands the product line to 128Mbit.  Everspin says that the combination of increased density with up to 233 megabytes/second full read and write bandwidth means that system designers now have the option of merging code and data memory on the same device, reducing cost, power, and area.

The EM128LX is offered in two industry standard package types, a 24-ball BGA and 8-pin DFN. Everspin’s advanced Spin-transfer Torque MRAM (STT-MRAM) provides over 10 years of data retention, virtually unlimited write cycle endurance, and comes complete with the xSPI interface that supports NOR Flash and serial SRAM operating modes.

Everspin is now ready to ship engineering samples of the EM128LX, and volume production will start in the early part of 2023.
