Memristor Theory and Concepts
Although the concept of the memristor (an amalgamation of the words: memory and resistor) was introduced 50 years ago, only recently research community has started seriously investigating various properties and potential applications of this nonlinear two terminal electrical component. The absence of any reliable and practical physical device that can demonstrate the perceived behaviors of the memristor has been hindering the experimental work and the implementation of memristor based applications. Therefore, most of the research works are still at the analytical stage and depend on mathematical models or emulator circuits of the memristor. In this chapter, the fundamental concepts and the theoretical background of memristor are briefly illustrated to provide a background for the memristor models and emulator circuits to be presented in this book.
