English to French Tech/Engineering Patents E-fuse apparatus for controlling reference voltage required for programming/reading E-fuse macro in an integrated circuit via switch device in the same integrated circuit

Electrically programmable fuse (e-fuse) apparatuses which control a reference voltage required for programming/reading an e-fuse macro in an integrated circuit via a switch device implemented in the same integrated circuit.

The switch device connects the first power source to the e-fuse units when the e-fuse macro is operated under a programming mode. In addition, another claimed 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 connects the power source to the e-fuse units when the e-fuse macro is operated under a read mode, the power source is external to the integrated circuit, and the switch device is coupled to the power source via a specific pin of the integrated circuit.
