Dating from May 2008, this NPR story was done shortly after the discovery by Stan Williams and HP Labs of a memristive material. From the synopsis:
“The possibility of such a circuit element, known as the “memristor,” was first described in 1971, but no one was able to find a device with the properties of that [...]
The Memristive switch:
“The team conducted its experiments by building a nanoscale memristor switch – at 50 nanometers by 50 nanometers, it is the world’s smallest – that contained a layer of titanium dioxide (a chemical commonly used in both sunscreen and white paint) between two nanowires. As its name implies, titanium dioxide typically comprises [...]
What is a memristor? Memristors are basically a fourth class of electrical circuit, joining the resistor, the capacitor, and the inductor, that exhibit their unique properties primarily within the nanoscale. Theoretically, Memristors, a concatenation of “memory resistors”, are a type of passive circuit elements that maintain a relationship between the time integrals of current and [...]
The memristor abstract can be found [ here ]. HP Labs has finally created a working model of a Memristor. Kudos!
A reader who was (quote) “…browsing through various recent releases in the electronic reference “aisle” of Amazon, I came across this gem, a festschrift dedicated to Leon Chua from his 60th birthday, and thought you might be interested in the historical value. Partly since actual physical books on paper are becoming rarer and rarer.” [...]
