Everspin Tech EMD3D256M08G1-150CBS1R

EMD3D256M08/16B 256Mb DDR3 Spin-Transfer Torque Magnetic Random Access Memory (STT-MRAM) is a non-volatile memory that delivers non-volatility and high endurance at DDR3 speeds. The device supports DDR3 operation at rates up to 1333MT/Sec/Pin. It is designed to be fully compliant with all DDR3 DRAM characteristics, including on-die termination (ODT) and internal ZQ calibration, while offering the advantages of data persistence and extremely high write cycle endurance. Using spin-torque MRAM technology, no cell refresh is required, which greatly simplifies system design and reduces overhead. All control and address inputs are synchronized to a pair of externally supplied differential clocks, with input latching occurring at the clock crossover points. I/O is synchronized to a pair of bidirectional strobe signals (DQS, DQS̄). The device employs a RAS̄/CAS̄ multiplexed scheme and operates at 1.5V.
