Abstract
A decoder and driver circuit for producing an output voltage exceeding the power supply uses a CMOS decode circuit followed by NMOS output stage and pump circuit. The pump clock is derived from a controlled oscillator, and the oscillator is synchronized with the access cycle of the memory device in which the circuit is used, so retention of the high level output is assured for an indefinitely long cycle time.
