Abstract
An apparatus includes a semiconductor fuse array and a plurality of cores. The semiconductor fuse array is disposed on a die, into which is programmed configuration data. The array has a first plurality of fuses and a second plurality of fuses. The first plurality of fuses stores the configuration data in an encoded and compressed format. The second plurality of fuses stores first compressed fuse correction data that indicates locations and values corresponding to a first one or more fuses within the first plurality of fuses whose states are to be changed from that which was previously stored. The plurality of cores is disposed on the die, where each of the plurality of cores is coupled to the array and accesses all of the compressed configuration data during power-up/reset, for initialization of elements within the each of the plurality of cores.
