Editing Crossbar latch (section)

==Details==
The crossbar latch was introduced by HP Labs scientists in the [[Journal of Applied Physics]], which provides a basis for constructing [[logic gate]]s using memristors. The crossbar latch consists of a signal line crossed by two control lines.  Depending on the [[voltage]]s sent down the various lines, it can simulate the action of the three major [[logic gate]]s: [[AND gate|AND]], [[OR gate|OR]] and [[NOT gate|NOT]].

The abstract of the patent is as follows: {{Quotation|"A [[molecular]] crossbar latch is provided, comprising two [[Control system|control]] [[wire]]s and a [[signal (information theory)|signal]] wire that crosses the two control wires at a non-zero angle to thereby form a junction with each control wire. Each junction forms a switch and the junction has a functional [[dimension]] in [[nanometers]]. The signal wire selectively has at least two different [[voltage]] states, ranging from a 0 state to a 1 state, wherein there is an [[asymmetry]] with respect to the direction of [[current (electricity)|current]] flow from the signal wire through one junction compared to another junction such that current flowing through one junction into (out of) the signal wire can open (close) while current flowing through the other junction out of (into) the signal wire can close (open) the switch, and wherein there is a voltage [[Threshold voltage|threshold]] for switching between an open switch and a closed switch. Further, methods are provided for latching [[logic]] values onto [[nanowires]] in a logic array, for inverting a logic value, and for restoring a voltage value of a signal in a nano-scale wire.
