Abstract: An internal voltage generation circuit including a drive control signal generator and an internal voltage driver. The drive control signal generator generates a drive control signal in response to an active pulse signal and a drive signal. The internal voltage driver, electrically coupled to the drive control signal generator, divides a level of an internal voltage signal in response to the drive control signal to generate a division voltage signal, compares a level of the division voltage signal with a level of a reference voltage signal to generate the drive signal, and drives the internal voltage signal in response to the drive signal.
