INTERNAL VOLTAGE GENERATION CIRCUIT AND SEMICONDUCTOR DEVICE INCLUDING THE SAME

摘要

An internal voltage generation circuit includes a first control signal generation unit suitable for generating a first control signal activated to a level of a second external voltage when a first external voltage is activated, a second control signal generation unit suitable for generating a second control signal that equals the higher of the second external voltage and an internal voltage, and a voltage generation unit suitable for generating the internal voltage by performing a charge pumping operation based on the second external voltage and an oscillation signal while blocking a current flowing through a generation node from which the internal voltage is generated, based on the first and second control signals.
