Abstract:
The present invention relates to a VPP voltage generator that generates a stable VPP voltage. The VPP voltage generator of the present invention generates a stable VPP voltage. Therefore, power consumption can be saved, a precharge time of word line can be prevented from increasing and a tRCD characteristic can be improved. It is thus possible to improve the operational performance of semiconductor memory devices.
