Advancing in-memory Arithmetic Based on CMOS-integrable Memristive Crossbar Structures

Abstract

Memristive computing will be advantageous in large-scale, highly parallel mixed-mode processing architectures because processing can be performed directly within memristive memory architectures and intrachip communication can be implemented by a memristive crossbar structure with reconfigurable logic gates. Here we report on the development of a new concept for in-memory adders, using XOR functionality. Exploited memristive crossbar structures are based on memristive complementary resistive switches, e.g. TaOx, and BiFeO3.
