Emerging resistive switching memory technologies: Overview and current status

Resistive memory technologies, in particular redox random access memory (ReRAM), are poised as one of the most prominent emerging memory categories to replace NAND flash and fill the important need for a Storage Class Memory (SCM). This is due to low switching energy, low current switching, high speed, outstanding endurance, scalability below 10 nm, and excellent back-end-of-line CMOS compatibility. Furthermore, the analog aspects of memristors have opened the door for many novel applications such as analog math accelerators and neuromorphic computers. This paper provides an overview of resistive memory technologies and their current status, with a focus on redox RAM (ReRAM).
