Computing with hysteretic resistor crossbars

An architecture for nano-electronic computation based on crossbars of hysteretic resistors is presented. We show how such crossbars can implement inverting and non-inverting latches and sum-of-product logic functions, and give examples of a NAND gate, exclusive-OR gate, and half adder. Multiple hysteretic resistor crossbars may be combined to implement complex computational systems. The designs have been evaluated using SPICE (a general-purpose circuit simulation program), demonstrating the feasibility of implementation given a suitable nano-electronic substrate.
