ABSTRACT:
A fuse signature circuit for a microelectronic device includes a fuse circuit and a sensing circuit. The fuse circuit includes a fuse which can be cut electrically in response to a cut control signal, and the fuse circuit generates a fuse state signal indicating if the fuse has been cut. The sensing circuit generates an output signal responsive to the fuse state signal.
