Abstract
An integrated circuit includes fuse readout logic and first and second sets of fuses. One of the sets includes one or more primary fuses whose burn states represent respective bit values, and the other of the sets includes one or more secondary fuses whose burn states are indicative of the bit values stored in the primary fuses. The fuse readout logic is configured to read the bit values by sensing the burn states of the primary fuses, and to conditionally correct the read bit values by sensing the burn states of one or more of the secondary fuses.
