ABSTRACT:
This disclosure concerns a semiconductor device that includes a booster portion including first switches and first capacitors; and a voltage converter comprising boosting stages each of which includes a second capacitor whose one end is connected to a first voltage source via a second switch and whose other end is connected to a reference voltage via a third switch, the second capacitor being charged on the basis of a voltage difference between the first voltage source and the reference voltage, and comprising fourth switches each of which is provided between two of the boosting stages to control the number of the second capacitors connected in series between a second power source and the other ends of the first capacitors according to the voltages of the first and second voltage sources, the voltage converter outputting clock signals with phases opposed to each other to adjacent ones of the first capacitors.
