ABSTRACT:
Various embodiments of the present invention are directed to electronic means for reading the content of a nanowire-crossbar memory. In one embodiment of the present invention, a microscale or sub-microscale signal line is interconnected with one set of parallel nanowires emanating from a nanowire-crossbar memory by configurable, nanowire-junction switches. The microscale or sub-microscale signal line serves as a single-wire multiplexer, allowing the contents of any particular single-bit storage element within the nanowire-crossbar memory to be read in a three-cycle READ operation.
