Memristor
Updated: 04/26/2017 by Computer Hope
First theorized in 1971 by Leon Chua, the memristor is the fourth fundamental circuit element, capable of making a non-linear relationship between electric charge and magnetic flux linkage. It was considered a missing non-linear passive two-terminal electrical component.
The electrical resistance of a memristor varies based on the history of electrical current flowing through the device. A memristor "remembers" its most recent electrical resistance when power is turned off, making it a form of non-volatile memory.
