Abstract
An internal voltage generator for generating a back bias voltage includes a back bias voltage pumping block for comparing a reference voltage with a feedback back bias voltage to generate a back bias enable signal and the back bias voltage in response to an activated self refresh signal and a back bias voltage discharge controlling unit for discharging the back bias voltage into a ground voltage in response to the activated self refresh signal and the back bias enable signal.
