ABSTRACT:
A semiconductor memory device includes a data input driver and a data output driver for receiving an external power supply voltage, and for inputting and outputting data, respectively; and a voltage detector for detecting the external power supply voltage to generate a detection signal, wherein a drive current of each of the data input driver and the data output driver is controlled by the detection signal.
