ABSTRACT:
A semiconductor device includes a voltage step-up circuit and a control circuit. The voltage step-up circuit includes at least a first capacitor and a second capacitor which generate an internal power supply voltage. The control circuit controls the voltage step-up circuit. The control circuit connects the first and second capacitors in series to perform a first voltage step-up operation and connects the first and second capacitors in parallel to perform a second voltage step-up operation. The voltage step-up circuit generates a first stepped-up voltage in the first voltage step-up operation and generates a second stepped-up voltage in the second voltage step-up operation. The circuit area of the voltage step-up circuit with a plurality of stepped-up levels is reduced.
