Abstract
An internal voltage generation circuit comprising: a first voltage generator buffers a first reference voltage from a first to a second time point and integrates the first reference voltage after the second time point to generate a first initial voltage, a divider outputs a second initial voltage by dividing the first initial voltage from the first to the second time point and to outputs the first initial voltage as the second initial voltage after the second time point, a selector selects and output the second initial voltage or a second reference voltage based on a comparison of level of a feedback voltage and the second reference voltage, and a second voltage generator generates an internal voltage depending on a result of comparing levels of an output voltage of the selector and the feedback voltage, and to generates the feedback voltage by dividing the internal voltage.
