Abstract
A semiconductor device includes a charge pump circuit suitable for generate an output voltage by pumping an input voltage according to first and second main clocks; a voltage detection circuit suitable for generating a comparison signal by comparing the output voltage with a reference voltage; and a driving control circuit suitable for generating the first and second main clocks according to first and second external clocks during an activation time period of the comparison signal while controlling a transition sequence such that the second main clock transitions after the first main clock transitions.
