2Mb Spin-Transfer Torque RAM (SPRAM) with Bit-by-Bit Bidirectional Current Write and Parallelizing-Direction Current Read

A 1.8V 2Mb spin-transfer torque RAM chip using a 0.2 μm logic process with an MgO tunneling barrier cell demonstrates the circuit technologies for potential low-power non-volatile RAM, or universal memory. This chip features an array scheme with bit-by-bit bidirectional current write to achieve prop... View More
