Abstract
A semiconductor device includes a SRAM circuit. The SRAM circuit includes: a memory array having a plurality of memory cells arranged in a matrix; a ground interconnection commonly connected to each of the memory cells; and a first potential control circuit for controlling a potential of the ground interconnection depending on an operation mode. The first potential control circuit includes a first NMOS transistor and a first PMOS transistor connected in parallel to each other between a ground node providing a ground potential and the ground interconnection.
