Magnetoresistive Random Access Memory (MRAM) Everspin Technologies Magnetoresistive Random Access Memory (MRAM) delivers significantly long data retention of >20 years and unlimited endurance. The data is automatically protected on power loss by low-voltage inhibit circuitry to prevent writes with voltage out of specification. These MRAM devices feature a 1 transistor – 1 magnetic tunnel junction (1T-1MTJ) architecture. Everspin MRAM products consist of serial SPI MRAMs and parallel interface MRAMs. The serial SPI MRAMs offer ideal memory for applications that must store and retrieve data and programs quickly using a minimum number of pins. The parallel interface MRAMs are SRAM compatible with 35ns/45ns access timing and unlimited endurance.
