Customizable circuitry

Claim 1

A multi-layer programmable electrical interconnect for connecting electrical components comprising: an X-conductor layer comprising a plurality of substantially parallel channels, each channel including a plurality of electrically conductive segments of substantially uniform length arranged end-to-end, a majority of segment ends in said X-conductor layer extending to a customization surface of said interconnect; a Y-conductor layer comprising a plurality of substantially parallel channels, each channel including a plurality of electrically conductive segments of substantially uniform length arranged end-to-end, a majority of the segment ends in said Y-conductor layer extending to said customization surface; the X-conductor layer and Y-conductor layer being positioned so that the channels of the X- and Y-layers overlap; a plurality of programmable junctions formed on the customization surface in a regular pattern, each programmable junction comprising segment ends of two adjacent X-conductor layer segments in the same X-conductor layer channel, and segment ends of two adjacent Y-conductor layer segments in the same Y-conductor layer channel, the segment ends in each programmable junction being positioned whereby selective electrical linkage can be accomplished on the customization surface between all combinations of segment ends forming the programmable junction, thereby permitting selective X to X, Y to Y, and X to Y linkage between the segment ends forming each programmable junction, as well as combinations thereof.
