begood Posted April 10, 2010 Report Posted April 10, 2010 (edited) Described in 1971, made in 2008: 'memristors' promise a computer revolution.High-school physics students grappling with the delights of capacitors, inductors and resistors will be groaning into their exercise books. Electronics experts in California have finally succeeded in proving the existence of a fourth fundamental unit of electronic circuits: the 'memristor'.The existence of the memristor, short for 'memory resistor', was first suggested in 1971, but only now have researchers succeeded in creating a real, working example. They hope that the new components could revolutionize computing, promising an end to frustrating waits for your computer to boot up."A memristor is essentially a resistor with memory," explains Stan Williams of HP Labs in Palo Alto, California, who reports the memristor's creation in this week's Nature1. "The actual resistance of the memristor changes depending on the amount of voltage and the time for which that voltage has been applied to the device."That means that a computer created from memristive circuits can 'remember' what has happened to it previously, and freeze that memory when the circuit is turned off. This quality could allow computers to turn off and on again in an instant, as all the components could revert to their last state instantly, rather than having to 'boot up'. http://www.physorg.com/news190016024.htmlFound: the missing circuit element : Nature News Edited April 10, 2010 by begood Quote
Cheater Posted April 10, 2010 Report Posted April 10, 2010 Frumos, o pagina grea de istorie scrisa in zilele noastre...as fi fost si mai bucuros daca ar fi sunat "Un grup de Cercetatori din Romania..."...nu ca nu ar exista posibilitatea sa fi fost si vreun roman p'akolo si daca ar fi fost...l-ar fi facut uitat....Poate nepotii nostri vor reusi mai multe in sensul asta...
