Business Landscape for Memresistor Electronics

Memresistor (i.e. memory resistor) electronics is defined by materials which have a memory of previously applied voltages or currents. Since the late 1990’s many different companies including Samsung, Micron Technology, Sharp, Hewlett- Packard, and Unity Semiconductor have been working with phase change, solid electrolyte, and metal oxide materials having memresistor characteristics to produce “transistor-less” memory cells or to introduce new concepts in computing and neuromorphics. This article reviews the patents and companies related to the memresistor concept.
