We present the design and implementation of a full adder circuit that exploits the natural flow of current through nanowires and More-than-Moore nano-devices in two dimensional crossbars. We evaluate the speed and energy efficiency of our design and compare it to equivalent one-bit adder designs using CMOS and nanoscale memristors. Our memristive full adder circuit has been shown to be an order of magnitude faster and more energy-efficient than equivalent CMOS designs. Our circuit is an order of magnitude more compact that equivalent CMOS designs. We also argue that our design occupies less area and is faster than competing memristor designs.
