Abstract
A programmable CMOS device includes a PFET and an NFET that have a common floating gate. Depending on the configuration, the programmable CMOS device can be programmed, erased, and re-programmed repeatedly. The programming, erasure, and/or reprogramming can be effected by injection of electrons and/or holes into the floating gate. The programmable CMOS device can be employed as a fuse or an antifuse, to program a floating gate of another device, and/or to function as a latch. The programmable CMOS device can be formed employing standard logic compatible processes, i.e., without employing any additional processing steps.
