In one embodiment of the present invention, a nanoscale latch is implemented by interconnecting an enable line, two control lines, and a pull-down line, when needed, to a signal line carrying encoded binary values to be latched and subsequently output. The enable line is interconnected with the signal line through a field-effect-transistor-like nanoscale junction. Both control lines are interconnected with the signal line through asymmetric-switch nanoscale junctions of like polarities. The pull-down line, when needed, is interconnected with the signal line through a resistive nanoscale junction. Inputting a sequence of signals to the enable and control lines allows a value input from the signal line to be stored and subsequently output to the signal line. In various additional embodiments, an array of nanoscale latches can be implemented by overlaying enable and control lines, and a pull-down line when needed, over a set of parallel nanowires.
