Memristor

A memristor is a special type of electrical circuit, like a switch, that can remember a charge that has gone through it. When you turn a switch on and off, it just turns the same way each time. But with a memristor, it remembers if it has been turned on or off. For instance, if you turn the memristor on and then off, the next time you turn it back on, it will already be in an "on" state, because it remembers that it has already been switched on before. Memristors are used to help computers and other electronic devices remember things like patterns and processes, so they can do their jobs more efficiently.
