ABSTRACT:
A FAMOS memory bit (40) is protected from voltage spike caused by an electrostatic discharge or otherwise by an ESD protection circuit (12). Responsive to a voltage spike on V.sub.pp, the ESD protection circuit (12) couples the drain of the FAMOS memory bit (40) to V.sub.cc or another high capacitance node.
