US Patent 7629694 - Mem-resistor crosswire circuit interface

There is an increasing interest in reconfigurable logic and other circuit architectures to achieve a higher flexibility in computing. This patent teaches mem-resistor thin films having programmable resistance characteristics used to interconnect arrays of crosswire grids for electronic devices such as memory arrays, computational devices, and pattern recognition systems. Claim 1 reads:

1. A system comprising:

a first crosswire array including first input wiring and first output wiring;

a second crosswire array including second input wiring and second output wiring, wherein the first crosswire array and second crosswire array are provided on or above the same side of a first substrate; and

a second substrate opposing the first substrate and including interconnection tips and circuit elements used to electrically connect the first crosswire array and the second crosswire array,

wherein at least one of the first crosswire array and second crosswire array include a thin film with a programmable resistance.
