US Patent 7319416 - Tunnel resistor addressing of nanowire crossbars

http://www.freepatentsonline.com/7319416.html

This patent from Hewlett Packard teasches using tunneling resistance junctions as an addressing interface between microscale and nanoscale wires. Claim 10 reads:

10. A method for addressing signal lines in a mixed microscale/nanoscale demultiplexer, the method comprising: determining a number of signal lines that need to be addressed; determining a signal margin needed between a signal output to a selected, addressed signal line and any signal output to a non-selected, addressed signal; and implementing a tunneling-resistor-junction-based encoder-demultiplexer to address the number of signal lines.
