ABSTRACT:
A single, relatively simple, circuit which provides programming supply voltages for the programming circuits of a typical PAL type programmable logic array with minimal die size requirements. The invention includes a voltage charge pump circuit for providing a first voltage on a first output bus in response to a first supply voltage and an input pulse. The first output voltage provided on the first output bus is greater than the first supply voltage. The invention further includes a first circuit for switching the first supply voltage onto a second output bus in response to a first set of programming signals. A second circuit is included for switching a second supply voltage onto a second output bus in response to a second set of programming signals.
