Abstract
A semiconductor memory device, in which the output of an internal supply voltage is stable, is provided. The semiconductor memory device includes a memory cell array block, a differential amplifier, using a reference voltage and an internal supply voltage fed back from the memory cell array block as inputs, an internal supply voltage driver for supplying an internal supply voltage to the memory cell array block in response to the output of the differential amplifier, a pull down circuit for pulling down the output port of the differential amplifier in response to a control signal having a predetermined pulse, and a control signal generating circuit for generating the control signal.
