Abstract

An electrically programmable fuse (e-fuse) apparatus includes an e-fuse macro and a switch device. The e-fuse macro is disposed in an integrated circuit, and has a plurality of e-fuse units. The switch device is disposed in the integrated circuit, and has an output node coupled to the e-fuse units and a first input node coupled to a first power source which supplies a first reference voltage acting as a programming voltage of the e-fuse macro. The switch device connects the first power source to the e-fuse units when the e-fuse macro is operated under a programming mode.
