Companies develop nanotech RAM chips

Nantero has created NRAM - the "N" stands for both nanotechnology and nonvolatile - a high-density RAM chip that saves its contents when a device is turned off or loses external power. Nantero manufacture its chip with carbon nanotubes, cylindrical structures consisting of hexagonal graphite molecules. Carbon nanotubes are up to 100 times stronger but one-sixth the weight of a steel object the same size. Because of nanotubes\´ strength, NRAM undergo many more read-write processes than other types of nonvolatile memory. The nanotubes also offer better electrical conductivity than many other materials frequently used in chips and thus enable faster performance.
