A new type of nonvolatile memory based on carbon nanotubes has dramatically lower power requirements than current technology. It uses the nanotubes to read and write data to small islands of phase-change materials, which store information. With further development, the new technology could extend battery life in mobile devices and also make desktop computers more efficient.

Nonvolatile memory stores information even when the power is switched off. The standard technology for it, flash memory, is used in smart phones, cameras, USB sticks, and fast-booting netbook computers.
