Abstract
A semiconductor device includes a SRAM (Static Random Access Memory) circuit. The SRAM circuit includes a static memory cell, a word line coupled with the static memory cell, a pair of bit lines coupled with the static memory cell, a first interconnection coupled with the static memory cell, and supplying a first potential, a second interconnection coupled with the static memory cell, and supplying a second potential lower than the first potential, a first potential control circuit controlling a potential of the second interconnection, and a second potential control circuit controlling a potential of the first interconnection. The SRAM circuit includes, as an operation mode a first operation mode for reading data from the SRAM circuit, or for writing data into the SRAM circuit, and a second operation mode for reducing power consumption than the first operation mode.
