Reconfigurable Stateful nor Gate for Large-Scale Logic-Array Integrations

This brief presents a stateful logic gate based on memristive devices that functions as high-fan-in NOR gates. The proposed logic structure executes multiple implications concurrently in a single step and thus enables fast logic operations reducing the number of pipeline steps. By mapping the logic units to the field-programmable nanowire interconnect fabric, a reconfigurable 2-D logic array for general-purpose functions can be implemented by configuring nanowire crossbar switches.
