Internal voltage generation circuit and system including the same

Abstract

An internal voltage generation circuit may be provided. The internal voltage generation circuit may include a first internal voltage generation circuit configured to provide a reference internal voltage to either an internal voltage control circuit or a node at which an output internal voltage is generated. The internal voltage generation circuit may include a second internal voltage generation circuit configured to change a level of the output internal voltage. The internal voltage generation circuit may include an internal voltage control circuit configured to compare the reference internal voltage with the output internal voltage and control the first and second internal voltage generation circuits to change the level of the output internal voltage according to a comparison.
