4Mb MRAM - Parallel and Serial Interface

4Mb Parallel Interface MRAM

Everspin 4Mb 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 out of specification. To simplify fault tolerant design, the MR4A16B includes internal single bit error correction code with 7 ECC parity bits for every 64 data bits.

Commercial, Industrial or AEC-Q100 Grade 1 Qualified options are available. 

 

 4Mb Serial SPI Interface MRAM

Everspin Serial SPI MRAM has EEPROM and serial Flash compatible read/write timing with no write delays and unlimited read/write endurance. Unlike other serial memories, the Everspin Serial SPI MRAM family both reads and writes randomly in memory with no delay between writes.

Commercial, Industrial or AEC-Q100 Grade 1 Qualified options are available.
