Molecular-junction-nanowire-crossbar-based inverter, latch, and flip-flop circuits, and more complex circuits composed, in part, from molecular-junction-nanowire-crossbar-based inverter, latch, and flip-flop circuits

A nanoscale latch comprising:

• an enable input nanowire signal line;
• an output nanowire signal line;
• and
• junction components programmed into the molecular-junction-nanowire crossbar to invert the input nanowire signal line to the output nanowire signal line when the enable input nanowire signal line is in an ON state and otherwise maintain the state of the output nanowire signal line.

A nanoscale inverting transparent latch comprising:

• a molecular-junction-nanowire crossbar;
• an input nanowire signal line D;

• and
• pEETs, nFETs, and connections selectively configured at molecular-junction-nanowire crossbar junctions to invert the input nanowire signal line D to the output nanowire signal line {overscore (Q)} when the enable input nanowire signal line G is in an ON state and its complement input nanowire signal line {overscore (G)} is in an OFF state, and, when G is in an OFF state and {overscore (G)} is in an ON state, maintain the state of output nanowire signal line {overscore (Q)}.

A nanoscale flip-flop comprising:

• a molecular-junction-nanowire crossbar;
• a first nanoscale latch programmed into the molecular-junction-nanowire crossbar to produce an output nanowire signal line;

A nanoscale latch with asynchronous {overscore (preset)} comprising:

• a first nanoscale 3-state inverter;
• a nanoscale nand circuit receiving, as input, a signal output from the first nanoscale 3-state inverter;
• and
• a second nanoscale 3-state inverter receiving, as input, a signal output from the nanoscale nand circuit and outputting a signal input to the nanoscale nand circuit.

A nanoscale latch with asynchronous clear comprising:

• a first nanoscale 3-state inverter;
• a nanoscale nor circuit receiving, as input, a signal output from the first nanoscale 3-state inverter;

• at least one output nanowire signal line;
• and
• transistors and connections selectively configured, at junctions within the molecular-junction-nanowire crossbar, to implement at least one 3-state inverter used, along with one of additional Boolean logic, one or more additional 3-state inverters, and a combination of additional Boolean logic and one or more additional 3-state inverters, to implement, within the molecular-junction-nanowire crossbar, a state-preserving circuit.
