Lower-power semiconductor memory device

Lower-power semiconductor memory device

A logic circuit in a system LSI (Large Scale Integrated Circuit) is provided with a power switch so as to cut off the switch at the time of standby, reducing leakage current. At the same time, an SRAM (Static Random Access Memory) circuit of the system LSI controls a substrate bias to reduce leakage...
