Abstract

A low power CMOS array cell for use in a PLD device is disclosed. The cell utilizes controlled avalanche injection at the p-n junction of a transistor in the CMOS cell for programming and erasing, resulting in lower voltages than with Fowler-Nordheim tunneling and lower currents than channel hot carrier injection during program and erase. A depletion transistor having a gate connected to its source has a source-drain path supplying current to the CMOS cell to limit current required during avalanche injection.
