An Efficient Memristive Alternating Crossbar Array and The Design of Full Adder

Abstract

Memristor is one of the most promising emerging technologies to solve the von Neumann bottleneck problem due to its non-volatile and binary characteristics. This paper studies the design method of high efficiency logic circuit based on memristor. First, a Multiple Input Multiple Output (MIMO) logic circuit de-sign scheme based on IMPLY and AND logic is proposed, which can derive multiple new efficient logic operation methods and complete complex logic with fewer steps and memristors. Second, in order to perform rapid interactive operations between different rows, an alternating crossbar array structure is designed which can quickly complete cross-row logic operations. Finally, a high-efficient Full Adder (FA) based on MIMO logic and alternating crossbar array is proposed. To accomplish32-bit add operation, the proposed FA needs 160memristors and only 41 steps. Compared with the state of art FA, our work has faster execution speed and fewer memristors.
