4. Memristor-Based Logic Circuits

Amongst several emergent applications of the memristance switching phenomenon, the implementation of logic circuits is gaining considerable attention. Memristor-based logic circuits open new pathways for the exploration of advanced computing architectures as promising alternatives to conventional integrated circuit technologies. However, up to now no standard logic design methodology exists, since it is not immediately clear what kind of computing architectures would in practice benefit the most from the computing capabilities of memristors. This chapter addresses memristive logic circuit design and computational methodologies, aiming to approach this novel area of research while motivating for further research on innovative design strategies, which comply with emerging technologies. First, a summary of the most recognized memristive logic circuit design concepts is provided. Then two novel logic design paradigms are presented, which aim to address several drawbacks of other existing design concepts in the literature, and to facilitate the incorporation of memristors in currently established logic circuit architectures. Thus they could be promising candidates to be used in future electronic systems design. The proposed design paradigms are validated through SPICE-based simulations for a variety of complex combinational logic circuits.
