A Memristor is a two-terminal electronic device whose resistance varies based on the amount of charge that has flowed through it. The memristor was first proposed in 1971 by circuit theorist Leon Chua. The memristor’s resistance depends on the history of the current that has flowed through it. When the current is first applied, the memristor has a high resistance. As the current flows, the resistance gradually decreases. If the current is removed, the memristor’s resistance remains low until the current is applied again, at which point it returns to its high-resistance state. The memristor is a fundamental circuit element, like the resistor, capacitor, and inductor.
Some of the emerging trends in memristors include the use of memristors for non-volatile memory applications, the use of memristors for neural networks, and the use of memristors for energy-efficient computing.
