Multi-level programming of memristor in nanocrossbar

Abstract

Utilizing memristor to obtain multi-level memory in nano-crossbar is a promising approach to enhance the memory density. In this paper, we proposed a solution for multi-level programming of memristor in nanocrossbar, which can be implemented on nanocrossbar without the need for extra selective devices. Meanwhile, using a general device model, this solution is demonstrated to be adaptive to a wide range of memristors that have been experimentally fabricated through HSPICE simulation.
