Memristor Crossbar Based Programmable Interconnects

The memristor is a novel non-volatile device having a large variable resistance range. Physical memristors can be laid out in a high density grid known as a crossbar. In this paper we propose a memristor crossbar based static routing switch design. We logically connect two wires within a crossbar by setting their corresponding cross-point memristor to a low resistance state. Conversely we logically disconnect the wires by setting the corresponding memristor to a high resistance state. Our evaluations show that the proposed static switch consumes extremely low power and has a high density compared to existing designs.
