Abstract

A circuit 10 coupled to, e.g., a two-device 12, 14 electrically programmable read-only memory 15 includes the combination of a gated diode 16 and a depletion-mode device 18 to form a variable protect circuit to protect a floating gate 20 and its insulator from damage or data alteration by accidental electrostatic discharge through a transistor control gate electrode 22 (Fig. 1).
