85 Memristor: Bryond Moore's Law and Digital Computing

Every person with an electronics background will be familiar with the three fundamental circuit elements - the resistor, the capacitor, and the inductor. These three elements are defined by the relation between two of the four fundamental circuit variables - current, voltage, charge and flux. In 1971, Leon Chua reasoned on the grounds of symmetry that there should be a fourth fundamental circuit element which gives the relationship between flux and charge. He named this circuit element the memristor, which is short for -memory resistor. In May 2008, researchers at HP Labs published a paper announcing a model for the physical realization of the memristor.

In this work, we present the basic working of memristor by using some equations given in the paper. These equations are obtained by replacing the non linear resistor in the four element Chua's circuit with a memristor. Hence, these chaotic circuits use only the four basic circuit elements. Moreover one of these circuits has only one negative element in addition to the nonlinearity.
