Abstract: An example fuse error detection circuit configured to receive a first data set from a fuse array during a first fuse data broadcast and to encode the first data set to provide first signature data. The fuse error detection circuit is further configured to receive a second data set from the fuse array during a second fuse data broadcast and to encode the second data set to provide second signature data. The fuse error detection circuit is further configured to compare the first signature data and the second signature data and to provide a match indication having a value based on the comparison between the first signature data and the second signature data.
