A Compact Scheme of Reading and Writing for Memristor-Based Multivalued Memory

The multivalued memory achieved with memristors is a promising approach to enhance the memory density. Effective and compact methods of reading and writing for multivalued memories can significantly improve the performance of circuits. In this paper, we present a compact and efficient scheme of reading and writing for two memristors per transistor-based multivalued memory. With the VTEAM model of the memristor, the verification of feasibility of our reading operations and writing operations for multivalued memory is achieved through HSPICE simulation.
