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.
