Patent ID: 8841746

Claim:
An integrated circuit comprising a programmable antifuse link, comprising: a printed circuit board; an integrated circuit die and a package comprising a power supply carried by the printed circuit board; the package having first and second power supply lead fingers; the die comprising first and second bond pads configured for connection to respective first and second power supply lead fingers on the package; a first bond wire connecting the first power supply lead finger of the package to the first bond pad of the die; and an antifuse link located within the die selectively connecting the first and second power supply bond pads for electrically connecting the first and second power supply bond pads together, wherein the antifuse link includes: a first electrical connection to the first bond pad via a first portion of a first metal layer within the die, a second electrical connection to the second bond pad via a second portion of the first metal layer, wherein the first and second portions of the first metal layer are electrically isolated from each other; a first programmable connection between the first portion of the first metal layer and a second metal layer within the die; and a second programmable connection between the second portion of the first metal layer and the second metal layer, wherein the second metal layer electrically connects the first and second programmable connections together.
