ABSTRACT:
A fuse-programmable control circuit has a master control circuit with a first fusible link that controls the feeding of power to a fuse-programmable memory. If output of signals from the fuse-programmable memory is not required, the first fusible link is cut. If output of signals from the fuse-programmable memory is required, the first fusible link is left uncut and the fuse-programmable memory is programmed by cutting one fusible link in each of a number of pairs of fusible links. In either case, no current can flow through the fuse-programmable control circuit.
