ABSTRACT:
The programmable interconnect structure of a field programmable gate array (see FIG. 4B) includes a plurality of wire segments extending in a first direction, the wire segments being collinear with respect to each other. An antifuse is disposed between each pair of adjacent wire segments so that the adjacent wire segments can be coupled together. Programming conductors for supplying a programming voltage onto selected wire segments extend in a second direction perpendicular to the first direction. The programming drivers for driving some of the programming conductors are disposed on one side (for example above) of the wire segments whereas the programming drivers for driving others of the programming conductors are disposed on the opposite side (for example below) of the wire segments. The pattern for programming drivers coupled to programming conductors alternates from one side of the wire segments to the other from column to column across the field programmable gate array.
