1Mb MRAM - Parallel and Serial Interface


1Mb Parallel Interface MRAM

The Everspin 1Mb Parallel Interface MRAM is SRAM compatible with 35 ns read/write timing and unlimited endurance. Data are always non-volatile for greater than 20 years.  Data are automatically protected on power loss by low-voltage inhibit circuitry to prevent writes with voltage below specification. 


1Mb Serial SPI 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.    


1Mb Quad Serial SPI 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, making it an attractive alternative to conventional parallel data bus interfaces in next generation RAID controllers, server system logs, storage device buffers, and embedded system data and program memory.
