ABSTRACT:
A zero power fuse circuit includes a latch means having two inputs, a first input being latched to ground and a second input being latched to V.sub.cc. The latch means is triggered either by a momentary contact of the first input to ground or by the momentary contact of the second input to V.sub.cc. A first embodiment includes two fuse element/capacitor pairs each coupled to one of the two inputs of the latch means. A second embodiment includes a pull-up transistor and a fuse element/capacitor pair, coupled to the first and second inputs respectively. A third embodiment includes a pull-down transistor and a fuse element/capacitor pair respectively coupled to the second and first inputs of the latch means.
