Nanowire Crossbar Implementations of logic Gates using configurable, tunneling resistor junctions

摘要

Various embodiments of the present invention are directed to nanowire crossbars that use configurable, tunneling resistor junctions to electronically implement logic gates. In one embodiment of the present invention, a method for implementing a logic gate comprises: providing a first layer of approximately parallel nanowires; interconnecting the first layer of approximately parallel nanowires with a second layer of approximately parallel nanowires through configurable, tunneling resistor junctions; selecting nanowires from among the first and second layer of nanowires to carry input and output electrical signals representing logical values; applying electrical signals representing input logical values to the input nanowires; and detecting an electrical signal representing an output logical value on the output nanowires.
