Abstract
A method for blowing a fuse in an IC device using the current generated by latchup. A fuse comprising a conductive material is caused to electrically open by directing a latchup current through the conductive material. The latchup current is generated by properly biasing parasitic bipolar transistors formed within the semiconductor substrate of the IC device, causing these parasitic transistors to latch up.
