ABSTRACT:
Disclosed is an internal voltage generator for applying stable working voltage to an internal circuit. The internal voltage generator comprises: a reference voltage generator for generating a reference voltage; a comparator for comparing the reference voltage with an internal voltage input into the internal circuit; a first switching element controlled by an output voltage of the comparator and coupled between a supply voltage terminal and an internal voltage input terminal in the internal circuit; a second switching element arranged in parallel with the first switching element and coupled between the supply voltage terminal and the internal voltage input terminal in the internal circuit; and an internal voltage controller for controlling a level of the internal voltage input into the internal circuit by controlling ON/OFF state of the second switching element according to an active mode and a standby mode.
