Abstract: Resistive random access memory (RRAM) is extensively concerned because of its excellent characteristics, namely, simple cell structure, high speed, low power and high density. The basic structure and operation principle of RRAM are presented. The promising RRAM technologies, such as 3D integration and multi-level storage, are discussed.

Key words: nonvolatile memory, resistive random access memory, resistance reversible change, 3D integration, multi-level storage
