Everspin Technologies EMD3D256M08/16B DRAMs

Everspin Technologies EMD3D256M08/16B DRAMs are non-volatile 256Mb DDR3 spin-transfer torque Magnetoresistive Random Access Memory (MRAM) with a maximum 667MHz clock frequency. These DRAMs offer non-volatility and high endurance at DDR3 speeds. The DDR3 STT-MRAM is a high-speed MRAM internally configured as an eight-bank RAM. These DRAMs are capable of DDR3 operation at rates of up to 1333MT/sec/pin. The EMD3D256M08/16B DRAMs are designed to comply with all DDR3 DRAM features, including On-Device Termination (ODT) and internal ZQ calibration. The spin-torque MRAM technology cell refresh is not required, simplifying system design and reducing overhead.
