1. An apparatus comprising:
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:
a first circuit configured to generate and sequentially update a fuse address to sequentially read the fuse data from the plurality of fuse sets; and
a second circuit configured to generate the first signal based on the fuse address generated by the first circuit,
wherein the first circuit is configured to change a frequency of updating the fuse address based on a first signal,
wherein the second circuit is configured to bring the first signal into a first state when the fuse address generated by the first circuit is in a first address range,
wherein the second circuit is configured to bring the first signal into a second state when the fuse address generated by the first circuit is in a second address range,
wherein the first circuit is configured to update the fuse address at a first frequency when the first signal is in the first state, and
wherein the first circuit is configured to update the fuse address at a second frequency lower than the first frequency when the first signal is in the second state.
