CONSTANT-WEIGHT-CODE-BASED ADDRESSING OF NANOSCALE AND MIXED MICROSCALE/NANOSCALE ARRAYS

摘要

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 (1700). 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-crosbar 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 included nanoscale memory arrays (1700) 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 (1308), a well-known class or error-control-encoding codes, as addressed-nanowire selection voltages applied to microscale output signal lines (1316-1319) of microscale/nanoscale encoder-demultiplexers that are selectively interconnected with a set of nanowires (1310-1315).
