Abstract
Storage circuitry () may be used to store the values of fuses () so that storage circuitry () can be read instead of fuses (). By accessing the fuse values from storage circuitry () rather than from fuses (), there will be no sense current to fuses () that may cause marginal fuse blowage for fuses that have not yet been blown. This helps to prevent the situation in which an unblown fuse is erroneously read as having been blown. The use of storage circuitry () thus significantly improves the reliability of fuse module (). For some embodiments, selection storage circuitry () may be used to determine whether storage circuitry () may be read or whether one of fuses () must be read in order to retrieve the desired current fuse value. The fuse value stored in storage circuitry () can also be used as direct hardware signals ().
