At the Berkley University (California) has been set up a nanotechnology prototype system for archiving , with unlimited duration and without silicon. A recent discovery made by researchers at the University of Berkeley could extend the “maturity” of digital memory media, making them practically “eternal”. Professor Alex Zettl and his team developed a digital memory prototype able to overcome the average length of life (between 10 and 30 years) of existing memory cards, up to one billion years and whose capacity is equal with a TB (terabyte). All without the use of silicon.

The experiment set up in laboratories at Berkeley (California) is not based on traditional technology microchips, but on nanotechnology. Basically, researchers have integrated a nanoscale particle of iron in a hollow carbon nano-tube: in the presence of an electrical signal, the nano-particle can be controlled and moved with extreme precision in the nano-tube whose ends – anchored electrodes-are the two symbols of the binary code (o and 1). This creates a system of programmable memory, which permit digital information recording and reproduction through conventional technology hardware.
