Memristor - Missing Fourth Electronic Circuit Element

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. Now, 37 years later, electronics have finally gotten small enough to reveal the secrets of that fourth element. The memristor, Hewlett-Packard researchers revealed on April 30, 2008 in the journal Nature, had been hiding in plain sight all along—within the electrical characteristics of certain nanoscale devices. They think the new element could pave the way for applications both near- and far-term, from nonvolatile RAM to realistic neural networks.

HP Labs has made a nano-scale device which stores data, explains previous anomalies in nano-device characteristics, and may be able to act as a synapse in analogue neural networks. It is also the first physical implementation of the memristor, a theoretical partner to resistors, capacitors and inductors invented in 1971.

cok enteresan bir haber, elektronik kitaplarimizin degismesi lazim belki de. Arti bir bilgi vereyim. Chua 1971 yilinda memristoru paperinda matematiksel olarak tanimlamis hatta paperi odul kazanmis. O zamanki teknolojiyle prototip devre yapip memristoru gostermis. Ilk bunu yapanin HP Lab olarak gosterilmesi dogru degil. HP Lab'in basarisi bugunun teknolojisiyle yani nanowirelar kullanarak memristor gelistirmesidir. Gelismeleri heyecanla izlemek lazim.
