ABSTRACT:
In a semiconductor integrated circuit device, a voltage setting circuit for setting a voltage level on the sub power source voltage line according to a reference voltage from a reference voltage generating circuit, is provided between a main power source voltage line and a sub power source voltage line. While a current consumption at the standby cycle is reduced, increase of the access delay is prevented. The voltage setting circuit includes a differential amplifier for differentially amplifying a voltage on the sub power source line and the reference voltages and a transistor responsive to an output of the differential amplifier for causing a current flow between the main and sub power source lines, or alternatively a diode-connected insulated gate type transistor receiving the reference voltage at a back gate thereof.
