| Abstract(in English) | A 1.8-V 2-Mb SPRAM (SPin-transfer torque RAM) chip using 0.2 μm logic process with 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 bi-directional current write to achieve proper spin-transfer torque writing of 100 ns, and parallelizing-direction current reading with low voltage bit-line that leads to 40-ns access time. |
