Claim:
1. A method for determining at least one of the unblown or blown states of a fuse in an electronic circuit, the unblown state being associated with a first range of resistances, and the blown state being associated with a second range of resistances, and wherein the fuse may be in an intermediate state having a resistance between the first and second first range of resistances, including: (a) comparing the resistance of the fuse to a plurality of different reference resistances, at least two of the different reference resistances each having an associated resistance value greater than the first range of resistances and less than the second range of resistances; and (b) determining at least one of the blown or unblown states of the fuse by requiring that at least one such state meet or exceed at least two separate comparisons.
