Abstract

An interconnection element for use in an user-configurable interconnection technology includes a normally shorted fuse element and a normally open antifuse element connected in series. The antifuse element is designed to program at a first current at a selected programming voltage. The fuse element is designed to program at a second current which exceeds the first current by a margin sufficient to prevent inadvertent programming of fuse elements during the antifuse element programming cycle. An interconnection network for use in integrated circuits and other connection networks includes a plurality of circuit nodes which may be selectively connected to one another. Each circuit node is connected to other circuit nodes using the interconnection element of the present invention which includes an antifuse element which programs at a programming voltage and a first current in series with a fuse element which programs at a second current having a magnitude larger than the first current.
