Memristive Computational Memory Using Memristor Overwrite Logic (MOL)

In this article, we present a novel logic design style, namely, memristor overwrite logic (MOL), associated with an original MOL-based computational memory. MOL relies on a fully digital representation of memristor and can operate with different memristive device technologies. Its integration in memristive crossbar arrays and computational memories allows the execution of bit and vector-level primitive logic operations in two computational steps at most. Promising features and performances are demonstrated through the implementation of N -bit full addition using the proposed MOL-based computational memory.
