A semiconductor device capable of efficiently generating an internal voltage according to the level of an external power supply voltage to be used. An internal charge supply node (ND53) and an internal charge supply node coupled to an output transistor (192) in a circuit for generating an internal voltage (Vpp) by a charge pump operation of a capacitive element (180, 184, 191) A charge pump capacitive element (187) responsive to a control signal is selectively coupled to one of the power supply nodes of the drivers (185, 186) for supplying electric charges to the capacitor via the capacitive element (191).
