Resistive random access memory and its applications in storage and nonvolatile logic

The resistive random access memory（RRAM） device has been widely studied due to its excellent memory characteristics and great application potential in different fields. In this paper, resistive switching materials,switching mechanism, and memory characteristics of RRAM are discussed. Recent research progress of RRAM in high-density storage and nonvolatile logic application are addressed. Technological trends are also discussed.
