Abstract:
An electrical fuse (E-fuse) circuit is disclosed, which relates to a technology for processing a failed part of the E-fuse circuit. The E-fuse circuit comprising: a boot-up controller configured to generate at least one fuse address and a sensing enable signal, an electrical fuse (E-fuse) array configured to include a plurality of fuse sets, and configured to output fuse data including failed data if a failure has occurred in an E-fuse of the plurality of fuse sets, based on the fuse address and the sensing enable signal, a fail controller configured to detect failed data from the fuse data, and output a failed signal and a failed address storage circuit configured to store a failed address from among the fuse addresses based on the failed signal.
