The future of computing is anything but conventional and memristors could hold the key to a new era in electronics, being a very promising technology for next-generation chips that need to be highly reconfigurable, scalable and energy-efficient. Memristors demonstrate many promising features, such as plasticity, analog nature, non-volatility, along with a low power consumption, high density, and excellent scalability, converting them to an emerging trend with an ever growing variety of potential applications. Memristors are literally ubiquitous; their applicability is as simple as it sounds: a memristor could essentially replace any resistor that has a particular role in a given circuit, thus improving the overall functionality and/or upgrading the circuit from static to programmable. In this chapter we present a brief overview of selected related applications aiming to highlight the really broad spectrum of on-chip workability of …
