ABSTRACT:
A semiconductor integrated circuit comprises a power supply voltage step down circuit and a MOS circuit group. The power supply voltage step down circuit is supplied with a power supply voltage and controlled by a standby control signal indicating an operating state or a standby state. The power supply voltage step down circuit outputs a first internal power supply voltage lower than the power supply voltage to an internal power supply line when the standby control signal indicates the operating state, and outputs a second internal power supply voltage lower than the first internal power supply voltage to the internal power supply line when the standby control signal indicates the standby state. The MOS circuit group including one or more MOS transistors which are supplied with the first or second internal power supply voltage from the internal power supply line to operate.
