Memristor

This is the talk of the town.This is considered as the greatest breakthroughs in the history of semiconductor technology.What is actually a memristor? A memristor(a  "memory resistor") is a passive two-terminal circuit element in which the resistance is a function of the time history of the current and voltage through the device. Memristor theory was formulated and named by Leon Chua in a 1971 paper.This is the wikipedia defination of memristor.The memristor is as fundamental an electronic component as the resistor, the inductor, and the capacitor.A memristor is a passive two-terminal electronic component for which the resistance (dV/dI) is proportional to the amount of charge that has flowed through the circuit. When current flows in one direction through the device, the resistance increases; and when current flows in the opposite direction, the resistance decreases. When the current is stopped, the component retains the last resistance that it had, and when the flow of charge starts again, the resistance of the circuit will be what it was when it was last active. The number of simultaneous calculations achieved by the memristors is the square of the number of transistors, tripling a 1000-transistor chip’s size by adding memristors would yield a thousandfold improvement in computing power with a negligible increase in power drawn.so,it will be very revolutionary in the semiconductor field.
