Patent ID: 7382177

Claim:
A voltage pump, comprising: a charging transistor responsive to a first control signal, said charging transistor operable to connect a node to a first voltage; a pumping capacitor responsive to a second control signal, said pumping capacitor operable to pump additional charge to said node; a pumping transistor responsive to a third control signal, said pumping transistor operable to connect said node to an output; a precharging transistor responsive to said first control signal to connect another node to said first voltage, wherein the conductivity of said pumping transistor is responsive to said voltage on said another node; a start-up transistor operable to prevent said another node from exceeding the voltage of said start-up transistor by more than a threshold voltage; a capacitor responsive to said third control signal to connect said another node to a second voltage; an isolation transistor operable to disconnect said pumping transistor from said output; and wherein said charging transistor, said pumping capacitor, said pumping transistor, said precharging transistor, said start-up transistor, and said capacitor are thin-gate transistors.
