ABSTRACT:
An internal voltage generator supplies a stable internal voltage without increasing standby current. The internal voltage generator includes an internal voltage driver for supplying an internal voltage based on a control signal, a feedback circuit for supplying a feedback voltage having a voltage level proportional to the internal voltage, a control signal generating circuit for generating the control signal to control the internal voltage driver such that the feedback voltage is maintained at a desired reference voltage, an auxiliary driving circuit for additionally supplying the internal voltage in response to the control signal, and an auxiliary driving control circuit for activating the auxiliary driving circuit only when it is expected to dissipate a large amount of a current.
