HP-Labs: Memristor

Unfortunately I can't spend time to update my blog in this period, but such a breaking new is very important to report on a computing web site. I need to read some more to provide good feedback on this matter, but it seems very promising. So, in the meanwhile, have fun looking at this link.

A nice picture on Memristor
...

A brief description stolen form here. Sorry ...
"In 1971, a University of California, Berkeley, engineer (Leon Chua) predicted that there should be a fourth element: a memory resistor, or memristor. But no one knew how to build one. Now, 37 years later, electronics have finally gotten small enough to reveal the secrets of that fourth element. The memristor, Hewlett-Packard researchers revealed today in the journal Nature ..."

" ... Chua deduced the existence of memristors from the mathematical relationships between the circuit elements. The four circuit quantities (charge, current, voltage, and magnetic flux) can be related to each other in six ways. Two quantities are covered by basic physical laws, and three are covered by known circuit elements (resistor, capacitor, and inductor), says Columbia University electrical engineering professor David Vallancourt. That leaves one possible relation unaccounted for. Based on this realization, Chua proposed the memristor purely for the mathematical aesthetics of it, as a class of circuit element based on a relationship between charge and flux. "
