1. A computing system for implementing at least one electronic circuit with gain comprising: at least one two-dimensional molecular switch array, said molecular switch array formed by assembling two or more crossed planes of wires into a configuration of devices, said device comprising a junction formed by a pair of crossed wires where one wire crosses another and at least one connector species connecting said pair of crossed wires in said junction, said junction having a functional dimension in nanometers and at least one switching capability provided by both (1) at least one connector species and said pair of crossed wires and (2) a configurable nano-scale wire transistor having a first state that functions as a transistor and a second state that functions as a conducting semiconductor wire; and at least one of said devices on one of said molecular switch arrays is configured to implement at least one of said electronic circuits, wherein specific connections are made to interconnect said devices and to connect said devices to two structures that provide voltages equal to a desired signal level for a high voltage level and a low voltage level.
