ABSTRACT:
Disclosed is a charge pump circuit that operates responsive to a test or general operation mode. The charge pump circuit includes at least one charge pump part. A voltage level sensing block generates a level sensing signal by sensing an output voltage. An oscillator generates complementary pulse signals responsive to the level sensing signal. And a selecting circuit block generates a selected voltage that is one of a high voltage and a supply voltage to the at least one charge pump part, the high voltage having a level higher than the supply voltage.
