Storage devices have a durability of one billion years

The new technology allows the production of memory up to 1 terabyte per square inch (6.4 square centimeters) and that data will be preserved for generations, while flash memory often degrades only after years.

Increasing the density of storing digital photos, music, videos . on silicon chips in USB drives or smartphones is like trying to stuff as many strawberries into a carton. The more they contain, the more fragile they are. Memory cards with a current density of 10-100 Gb / inch are only 10-30 years old and users need more secure technology for their personal devices.

US scientists have successfully tested the method of putting a nano iron molecule with the size of only 1 / 50,000 width of hair fibers into carbon nanotubes. This iron will move up and down in pipes to store and protect data effectively.

Detailed information about this invention will be announced by the American Chemical Society in mid-June.
