Abstract:
A voltage generation circuit includes a driver configured to generate an internal voltage by driving an external voltage depending on a driving signal; an amplifier configured to generate the driving signal depending on a result of comparing a reference voltage and a feedback voltage; and a switch configured to delay a decrease of the internal voltage by precharging a node of the amplifier with a predetermined voltage depending on a control signal.
