Abstract
A charge pump circuit includes a first plurality of capacitors, and a first precharge circuit. The first plurality of capacitors are connected in parallel to each other. The first plurality of capacitors receive clock signals to perform sequentially pumping operations which generate a first higher voltage from a power voltage supplied. The first precharge circuit precharges a predetermined number of capacitors in the first plurality of capacitors at the power voltage. The predetermined number is greater than one.
