Nantero has presented carbon nanotube memory chips, the company calls this technology nanotube-based, non-volatile random access memory (NRAM).
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.
Head over to Nature.com to learn more about NRAM. The first prototypes of products with NRAM should be ready by Summer 2006.
