Abstract: Disclosed herein is an apparatus that includes a fuse array circuit including a plurality of fuse sets each assigned to a corresponding one of a plurality of fuse addresses and configured to operatively store a fuse data, and a first circuit configured to generate and sequentially update a fuse address to sequentially read the fuse data from the plurality of fuse sets. The first circuit is configured to change a frequency of updating the fuse address based on a first signal.
