Semicondcutor integrated circuit device

Abstract

According to one embodiment, a semiconductor integrated circuit device is provided. The semiconductor integrated circuit device is provided with a plurality of booster circuits, a regulator and a plurality of switches. Each of the booster circuit receives an input voltage, boosts the input voltage, and generates a boosted voltage having a different value. The regulator is capable of generating a plurality of dropped voltages by dropping each boosted voltage from the booster circuits. The switches are connected between the booster circuits and the regulator. The switches provide the boosted voltages outputted from the booster circuits selectively to the regulator as a power-supply voltage.
