Nanotubes refine computer memory

Will computers that require no time to boot up become a reality? One company thinks the answer is yes, thanks to its carbon nanotube memory chips.

Nantero presented its achievement at the Emerging Technologies Conference in Cambridge, Massachusetts. It uses rolled-up tubes of carbon to make transistors, the on-off switches that carry digital information inside computing chips: strings of the nanotubes move up and down to represent the ones and zeroes of binary code. Unlike the electrons in normal electrical transistors, these nanotubes stay in place even when a computer is turned off.
