Abstract
Various embodiments of the present invention include methods for determining nanowire addressing schemes and include microscale/nanoscale electronic devices that incorporate the nanowire addressing schemes for reliably addressing nanowire-junctions within nanowire crossbars. The addressing schemes allow for change in the resistance state, or other physical or electronic state, of a selected nanowire-crossbar junction without changing the resistance state, or other physical or electronic state, of the remaining nanowire-crossbar junctions, and without destruction of either the selected nanowire-crossbar junction or the remaining, non-selected nanowire-crossbar junctions. Additional embodiments of the present invention include nanoscale memory arrays and other nanoscale electronic devices that incorporate the nanowire-addressing-scheme embodiments of the present invention. Certain of the embodiments of the present invention employ constant-weight codes, a well-known class of error-control-encoding codes, as addressed-nanowire selection voltages applied to microscale output signal lines of microscale/nanoscale encoder-demultiplexers that are selectively interconnected with a set of nanowires.
