Electronic components allowing their resistance to be controlled and reversibly switched between two or more values (memristive components or memristors) can be deployed in various application areas. These include e.g. data processing and storage (non-volatile memory), novel low-energy computing architectures (neuromorphic electronics / AI), as well as in the area of hardware-based protection from unauthorized access to data, circuits etc. (PUF: Physically Unclonable Functions).
