PM004MNIB

Short Description:

PM004 is a 4M Bit/512K Byte capacity SPI (Serial Single-Wire) interface STT-MRAM (Spin-Transfer Torque Magnetic Random Access Memory) chip. Its data is non-volatile with a retention time exceeding 10 years. The chip supports independent 1-bit SI (Serial Input) and SO (Serial Output) interfaces, allows continuous writing or reading of data bytes at its maximum clock frequency, and features zero write latency.
