New Memory Material May Hold Data For One Billion Years
Scientists are reporting an advance toward remedying this situation with a new computer memory device that can store thousands of times more data than conventional silicon chips with an estimated lifetime of more than one billion years. Their discovery is scheduled for publication in the June 10 issue of the American Chemical Society's Nano Letters, a monthly journal.
Alex Zettl and colleagues note in the new study that some of today's highest-density experimental storage media can retain ultra-dense data for only a fraction of a second. They note that William the Conqueror's Doomsday Book, written on vellum in 1086 AD, has survived 900 years. However, the medium used for a digital version of the book, encoded in 1986, failed within 20 years.
