Crossbar latch/Temp

The crossbar latch is a molecular-scale structure that may replace transistors as the major component of computers.

Developed by Hewlett-Packard, the crossbar latch consists of a signal line crossed by two control lines. Depending on the voltages sent down the various lines, it can simulate the action of the three major logic gates: AND, OR and NOT.
