Abstract
A semiconductor memory device with a power source voltage step-down circuit which generates a stepped-down voltage from electric power supplied from outside and supplies this stepped-down voltage to a memory cell array and peripheral circuits. Current switching device interposed in a circuit or circuits of the semiconductor memory device other than the memory cell array and a switch controlling signal generating means for generating a controlling signal in response to a signal from the outside are provided. The current switching device performs switching of current to flow through the circuit in response to a controlling signal.
