A semiconductor integrated circuit device includes: a boost circuit configured to boost power supply voltage so as to generate a boosted voltage; a voltage detecting circuit configured to detect the boosted voltage of the boost circuit and control ON/OFF of the boost circuit for keeping the boosted voltage at a certain level; and a gate circuit configured to set the voltage detecting circuit to be in such an inactive state that current passage thereof is shut off, thereby stopping the operation of the boost circuit while a load is separated from an output node of the boost circuit.
