New Memory Material May Hold Data For One Billion Years

By ACS PressPac

May 27, 2009

Alex Zettl and colleagues say enclosing an iron nanoparticle in a hollow carbon nanotube could serve as the foundation for a memory material for the next generation of iPods, smartphones, and other mobile devices. The scientists used electricity to control the nanoparticle, moving it back and forth to act as a programmable memory system, in that digital information could be recorded and played back with conventional computer hardware. The experimental memory device offers a storage capacity of 1 trillion bits of information and a lifetime of more than 1 billion years.

An increasing amount of digital images, music, and other data is being packed onto silicon chips, but the 10 to 100 gigabits of data per square inch on current memory cards only have a lifetime of 10 to 30 years.
