ABSTRACT:
A voltage regulator circuit for a semiconductor memory device includes a first internal source voltage generator for receiving a reference voltage and a column address strobe signal and for supplying an internal source voltage based on an external source voltage, and a second internal source voltage generator for receiving the reference voltage and a row address strobe signal and for supplementing the supply of the internal source voltage based on the external source voltage. The circuit separately controls the operation of the voltage regulator circuit in accordance with an operational condition of a semiconductor memory device to generate an internal power source having stable voltage, while decreasing stand-by current.
