256Kb MRAM - Parallel and Serial Interface

256Kb Parallel Interface MRAM

Everspin 256Kb MRAM is SRAM compatible with 35ns 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 out of specification. Everspin 256Kb MRAM is the ideal memory solution for applications that must permanently store and retrieve critical data and programs quickly.

 

 256Kb Serial SPI Interface MRAM

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.
