Abstract:
1. Crossbar circuitry for interconnecting a plurality of source circuits and a plurality of destination circuits such that data input to the crossbar circuitry from any of said plurality of source circuits can be output to any of said plurality of destination circuits, the crossbar circuitry comprising: a plurality of data input paths passing through said crossbar circuitry, each data input path being connectable to one of said plurality of source circuits and providing a plurality of word lines; a plurality of data output paths passing through said crossbar circuitry transverse to the plurality of data input paths, each data output path being connectable to one of said plurality of destination circuits and providing a plurality of bit lines; a crossbar cell associated with each intersection between one of said data input paths and one of said data output paths, each crossbar cell comprising:
