ABSTRACT:
An internal voltage generation circuit of a semiconductor device is disclosed. The internal voltage generation circuit comprises a reference voltage generator for generating a reference voltage having different levels depending on different operation modes of the semiconductor device, an active voltage generator for generating an active internal voltage of a level based on the reference voltage, a standby voltage generator for generating a standby internal voltage of a level based on the reference voltage, and an active voltage generation controller for controlling the active voltage generator such that the active voltage generator outputs the active internal voltage in a specific period after completion of a self-refresh mode.
