MAGIC - Memristor-Aided Logic

— Memristors are passive components with a varying resistance which depends on the previous voltage applied across the device. While memristors are naturally used as memory, memristors can also be used for other applications, including logic circuits. In this paper, a memristor only logic family, MAGIC (Memristor Aided LoGIC), is presented. In each MAGIC logic gate, memristors serve as an input with previously stored data and an additional memristor serves as an output. The topology of a MAGIC NOR gate is similar to the structure of a common memristor-based crossbar memory array. A MAGIC NOR gate can therefore be placed within a memory, providing opportunities for novel non-von Neumann computer architectures. Other MAGIC gates also exist (e.g., AND, OR, NOT, and NAND) and are described in the paper.
