Researchers at Arizona State University and other institutions have collaborated to create a nanomechanical device that operates as a reprogrammable logic gate in performing fundamental logic functions such as AND/OR and NAND/NOR. The logic function can be programmed dynamically by altering the operating parameters of the resonator. The device can access one of two stable steady states according to a specific logic function. This action is moderated by the noise floor, which can be directly adjusted or dynamically ?tuned? with an adjustment to the nonlinearity of the resonator. Hence, having direct control over the noise floor is not required. Achieving this capability with power consumption and size similar to the current CMOS logic gates is a step toward the practical realization of an alternative architecture that surpasses the limit at which current microprocessors can be scaled.
