Short for memory resistance, memristance is a property of an electronic component that
lets it remember (or recall) the last resistance it had before being shut off.
HP makes memory from a once-theoretical circuit Thirty-seven years ago, Leon Chua, a professor at the University of California at Berkeley, mathematically theorized that scientific symmetry demands that there should be a fourth fundamental circuit element.
HP Memristor FAQ It turns out that memristance is becoming stronger as the feature sizes in circuits are getting smaller. At some point as we scale into the realm of nanoelectronics, it will be necessary to explicitly take account of memristance in our circuit models in order to simulate and design electronic circuits properly.
Memristor mystery revisited: Your questions answered Flash and hard disk are non-volatile but very slow. There exists a significant opportunity for a new memory technology that is *both* fast and non-volatile. Memristor technology is an excellent candidate for this role.
