Patent ID: 6906504

Claim:
A semiconductor device comprising: a plurality of first terminals for respective capacitor connections; a second terminal for supplying a power supply voltage; a third terminal for supply a ground voltage; and a voltage booster circuit electrically connecting said first, second and third terminals, the voltage booster circuit boosts an input voltage by using a capacitor and generates a boosted voltage higher than said input voltage, the voltage booster circuit having an input terminal at which the input voltage is applied, an output terminal at which the boosted voltage is outputted, a plurality of N channel transistors electrically connected in series between said input terminal and said output terminal, a plurality of first P channel transistors each of which electrically connected with corresponding ones of said plurality of N channel transistors in parallel, and a controlling circuit that outputs control signals each of which controlling a conductive state of corresponding ones of said N channel transistors and corresponding ones of said P channel transistors, wherein the plurality of first terminals are respectively electrically connected to first electrodes of corresponding ones of said N channel transistors and first electrodes of corresponding ones of said first P channel transistors corresponding to said corresponding one of N channel transistors, wherein each of said N channel transistors is controlled to be in a conductive state different from a conductive state of an adjacent one of said N channel transistors, by said control signals, and wherein each of said P channel transistors is controlled to be in a conductive state corresponding to the conductive state of a corresponding one of said N channel transistors electrically connected thereto in parallel, by said control signals.
