Abstract: A voltage generation circuit includes a voltage control circuit configured to disable a high voltage driving signal, after generating a low voltage driving signal and the high voltage driving signal by comparing a reference voltage and an internal voltage after the start of a mismatching cancellation operation and a sensing operation, and a voltage supply circuit including a first driver having a first driving power and a second driver having a second driving power and configured to drive the internal voltage by selectively activating the first driver and the second driver based on the low voltage driving signal and the high voltage driving signal.
