Redox-based resistive switching devices (ReRAM) provide new hardware concepts which make it possible to break the von Neumann bottleneck and build a new computing system in the information. However, the materials for switching layers are various and mechanisms are quite different, these will block the further exploration for practical applications. This review tends to demonstrate different kinds of memristors fabricated with various materials, such as oxide, nitride and 2D materials. The electrical properties of those based on different materials are compared and the advantages of each are listed. It would give a guidance to the selection of materials of memristors.

ABSTRACTMetal-insulator-metal (MIM) resistive switching devices are being pursued for a number of applications, including non-volatile memory and high density/low power computing. Reported resistive switching devices vary greatly in the choice of metal oxide and electrode material. Importantly, the choice of both the metal oxide and electrode material can have significant impact on device performance, their ability to switch, and the mode of switching (unipolar, bipolar, nonpolar) that results. In this study, three metal oxides (Cu2O, HfOx, and TiOx) were deposited onto copper bottom electrodes (BEs). Four different top electrode (TE) materials (Ni, Au, Al, and Pt) were then fabricated on the various metal oxides to form MIM structures. Devices were then characterized electrically to determine switching performance and behavior. Our results show that the metal TE plays a large role in determining whether or not the MIM structure will switch resistively and what mode of switching (unipolar, bipolar, or non-polar) is observed.

AbstractTiOx-based resistive switching devices have recently attracted attention as a promising candidate for next-generation non-volatile memory devices. A number of studies have attempted to increase the structural density of resistive switching devices. The fabrication of a multi-level switching device is a feasible method for increasing the density of the memory cell. Herein, we attempt to obtain a non-volatile multi-level switching memory device that is highly transparent by embedding SiO2 nanoparticles (NPs) into the TiOx matrix (TiOx@SiO2 NPs). The fully transparent resistive switching device is fabricated with an ITO/TiOx@SiO2 NPs/ITO structure on glass substrate, and it shows transmittance over 95% in the visible range. The TiOx@SiO2 NPs device shows outstanding switching characteristics, such as a high on/off ratio, long retention time, good endurance, and distinguishable multi-level switching. To understand multi-level switching characteristics by adjusting the set voltages, we analyze the switching mechanism in each resistive state. This method represents a promising approach for high-performance non-volatile multi-level memory applications.
