Abstract

The invention discloses a non-volatile resistor change type memory with the self-rectification effect. The non-volatile resistor change type memory comprises an upper Pt electrode, a lower Pt electrode, a binary transition metal oxide thin film and a PtOx boundary layer, wherein the binary transition metal oxide thin film is positioned between the upper Pt electrode and the lower Pt electrode, and the PtOx boundary layer is positioned between the binary transition metal oxide thin film and the lower Pt electrode. The non-volatile resistor change type memory with the self-rectification effect has the advantages of simple structure, easy integration, low cost, compatible process with the traditional silicon planer CMOS, and the like, and is beneficial to the wide popularization and the application of the invention.

Description

technical field [0001] The invention relates to the technical field of microelectronic devices and memories, in particular to a nonvolatile resistance transition memory with self-rectification effect based on the resistance transition characteristics of binary transition metal oxides. Background technique [0002] Recently, resistive random access memory (RRAM) has become prominent due to its simple device structure (metal-insulator-metal), high device density, low power consumption, fast programming / erasing speed, etc. Advantages, so it has attracted great attention from large companies and research institutes at home and abroad. [0003] Resistance transition memory technology is based on the fact that the resistance of the material can be reversibly switched between a high resistance state and a low resistance state under voltage control. There are many types of materials that have been proved to have resistance switching properties: (1) organic polymers, such as polyimi...
