Novel Applications Enabled by Memristors [Guest Editorial]

Constant advances in semiconductor manufacturing have led to the ubiquitous presence of cheap and reliable computing devices in all aspects of our lives. However, further innovation exclusively based on scaling the CMOS technology feature size will not be sufficient in the coming years, as the well-known Moore's law is slowing down. While CMOS is not going to disappear, it will most likely be supported by several other innovative technologies with stronger performance in specific application scenarios. Among various novel technologies, memristors are emerging as promising devices for high-density memory arrays, neuromorphic computing, and, recently, logic and processing in memory. Recent research also revealed memristor sensitivity to gases and other chemicals. All these developments show that memristors have unexplored potential to shift the paradigm for several other applications.
