Abstract
A voltage generator for low power applications includes a circuit for generating, controlling and maintaining a high voltage for low power applications in an integrated circuit. The circuit includes separate standby and active circuits for pumping V.sub.CCP of a DRAM under different circumstances. The standby and active circuits operate independently of one another, but may operate simultaneously, to pump charge to V.sub.CCP. The standby circuit is generally a low power circuit activated in response to power up and leakage current conditions to maintain V.sub.CCP. The active circuit is generally a larger circuit and can pump more current. The active circuit is generally responsive to the word lines being driven. Accordingly, the voltage generator can maintain V.sub.CCP while minimizing power consumption in DRAM.
