Nanoscale shift register and signal demultiplexing using microscale/nanoscale shift registers

摘要

Methods for inputting a data-value pattern into a nanowire crossbar, for inputting a data-value pattern into a nanowire crossbar that support computer instructions stored in a computer-readable medium, and for distributing a received data value to each of a set of nanowires that support control logic implemented in logic circuits are provided. First and second nanoscale shift registers are employed, the first having output signal lines that form or interconnect with a first parallel set of nanowire-crossbar nanowires and the second having output signal lines that form or interconnect with a second parallel set of nanowire-crossbar nanowires. A first pattern of values is stored in the first shift register and a second pattern of values is stored in the second shift register using voltage signals below the WRITE voltage for junctions of the crossbar. Voltage signals greater than or equal to the WRITE threshold are applied for junctions of the crossbar to write the pattern of data values into the crossbar.
