❚ 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.
