ABSTRACT:
In a static random access memory for storing data in a plurality of memory cells constituting a memory cell array to which a specified electric current for activating each memory cell is supplied from a power source via a path, a P-channel MOSFET is provided as a switch on the path between the power source and the memory cell array. When reading or writing of data in memory cells is performed, the switch is turned on and a specified electric current for activating the memory cells is supplied to the memory cell via the path having the switch. Between the power source and the memory cell array is also provided an electric resistor connected in parallel with the switch. During a stand-by state of the memory cell array, the switch is turned off so that the above path is cut off, and a voltage of the power source is applied through the resistor to the memory cells. Consequently, the electric current supplied to the memory cells becomes smaller than when the electric current flows via the above path, whereby consumption of electricity is suppressed.
