Ultra-low Power Digital Memory

A group of engineers have replaced metal conductors with carbon nanotubes to create digital memory that uses 100 times less power than the ones that are currently used. This can provide more headroom for battery consumption so that a few more minutes of runtime can be squeezed (the processors and displays contribute to the larger fraction of battery consumption). Also, the memory manufactured from the use of carbon nanotubes allow for faster data transmission (although the source does not disclose how much it is faster than current memory).

This would improve current flash drives, RAM modules and SSDs but may cause such devices to cost an arm and a leg due to the cost of carbon nanotubes (SSDs may include another leg to the cost).
