Abstract: An electronic circuit is formed by closely spacing metallic gate and drain interconnects to a flexible portion of a source interconnect. A gate voltage results in electrostatic attraction and lateral mechanical movement of the flexible source interconnect portion and causes an electrical short between source and drain. VanderWaals attraction between contacting source and drain can be used to provide volatile switching (springy thicker source portion) and non-volatile switching (limp thinner source portion). In accordance with the invention, an easily fabricated, high speed, low power, radiation hard, temperature independent, integrated reconfigurable electronic circuit with embedded logic and non-volatile memory can be realized. The switch uses patterned interconnect material for its structure and can be incorporated to a 3D layered structure consisting of three dimensional interconnect in which different layers and portions of the circuits are linked through volatile and non-volatile switches.

Abstract: An electronic system includes a three terminal device having a light emitting portion and a magnetically sensitive portion. The magnetically sensitive portion is for modulating light emission from the light emitting portion. The device is a spin valve transistor having a light-emitting quantum well in its collector. The device can convert a magnetic digital signal to both an electrical digital signal and an optical digital signal, wherein either or both of these signals can be provided as a device output. The magnetically sensitive portion of the device is formed of a pair of magnetically permeable layers. When the layers are aligned electron current can pass through with sufficient energy to reach a quantum well where they recombine, generating light. The device may be used to read a magnetic storage medium, such as a disk drive. Or it can be used to provide a display or a memory array composed of single device magnetic write, optical read memory cells.
