Memristor found: HP Labs proves fourth integrated circuit elemen. In the memristor work, the researchers built on their extensive experience - Williams founded the precursor lab to IQSL in 1995 - in building and studying nanoscale electronics and architectures.
One goal of this work has been to move computing beyond the physical and fiscal limits of conventional silicon chips. For decades, increases in chip performance have come about largely by putting more and more transistors on a circuit. Higher densities, however, increase the problems of heat generation and defects and affect the basic physics of the devices. "Instead of increasing the number of transistors on a circuit, we could create a hybrid circuit with fewer transistors but the addition of memristors - and more functionality," Williams says.
Alternately, memristor technologies could enable more energy-efficient high-density circuits. HP Discovers Potential "God Particle" of Electronics. Silicon Valley is mostly a world of practical technology—applying principles from pure science to create handy gadgets.
But today, Hewlett Packard announced a new electrical component born of theoretical physics. The device, a nanoscale component called a "memristor," requires no power to retain data, which it can store more densely than a hard drive and access about as fast as a computer's RAM memory—potentially allowing it to replace both components in the future. Memristors can function in either a digital mode, in which a memory cell is "on" or "off," or in analog mode, in which each cell holds some value in between.
These values grow every time the cell receives an electrical signal, mimicking the way neurons in the brain build stronger memories the more they are stimulated. Memristor. Leon Chua has more recently argued that the definition could be generalized to cover all forms of 2-terminal non-volatile memory devices based on resistance switching effects although some experimental evidence contradicts this claim, since a non-passive nanobattery effect is observable in resistance switching memory. Chua also argued that the memristor is the oldest known circuit element with its effects predating the resistor, capacitor and inductor. The memristor is currently under development by various teams including Hewlett-Packard, SK Hynix and HRL Laboratories.
Leon O. Chua. Leon Ong Chua (/ˈtʃwɑː/; Chinese: 蔡少棠; pinyin: Cài Shàotáng; Pe̍h-ōe-jī: Chhòa Siáu-tông; born June 28, 1936) is an IEEE Fellow and a professor in the electrical engineering and computer sciences department at the University of California, Berkeley, which he joined in 1971.
Dr. Leon O. Chua contributed to nonlinear circuit theory and Cellular neural network (CNN). He is also the inventor and namesake of Chua's circuit and was the first to conceive the theories behind, and postulate the existence of, the memristor. Thirty-seven years after he predicted its existence, a working solid-state memristor was created by a team led by R. Stanley Williams at Hewlett Packard.

Stanley Williams 1 May 2008--Anyone familiar with electronics knows the trinity of fundamental components: the resistor, the capacitor, and the inductor. In 1971, a University of California, Berkeley, engineer predicted that there should be a fourth element: a memory resistor, or memristor. But no one knew how to build one. Memristor - GHN. From GHN Memristor Background The Memristor is the fourth fundamental 2 terminal electronic component alongside the Resistor, Capacitor and Inductor.
The name is a contraction for memory-resistor. IEEE Spectrum magazine had a feature article on this 'new' component in December 2008, pages 25-31. The Miraculous Memristor - Logic And Memory Plus Going Beyond Mo. Posted by Tom Foremski - April 19, 2010 I recently visited HP Labs and spoke with Stan Williams, senior fellow at Hewlett-Packard and director of Quantum Science Research, about an incredible semiconductor device -- the memristor.
Until fairly recently, the memristor, short for memory resistor, was a mythical electronic component. It had been predicted to exist by a mathematician, Leon Chua, a professor at UC Berkeley, in an 1971 paper. No one had made a memristor until Stan Williams and his team cracked it in 2008. The memristor can:
