Logic operations in memory using a memristive Akers array

In-memory computation is one of the most promising features of memristive memory arrays. In this paper, we propose an array architecture that supports in-memory computation based on a logic array first proposed in 1972 by Sheldon Akers. The Akers logic array satisfies this objective since this array can realize any Boolean function, including bit sorting. We present a hardware version of a modified Akers logic array, where the values stored within the array serve as primary inputs. The proposed logic array uses memristors, which are nonvolatile memory devices with noteworthy properties. An Akers logic array with memristors combines memory and logic operations, where the same array stores data and performs computation. This combination opens opportunities for novel non-von Neumann computer architectures, while reducing power and enhancing memory bandwidth.
