... Introduction The MR2A16A is a 4,194,304-bit magnetoresistive random access memory (MRAM) device organized as 262,144 words of 16 bits. The MR2A16A is equipped with chip enable (E), write enable (W), and output enable (G) pins, allowing for significant system design flexibility without bus contention. Because the MR2A16A has separate byte-enable controls (LB and UB), individual bytes can be written and read. ...
