Saw this come through my IEEE membership registered e-mail. Kind of interesting. Came out on September 3rd, but just got the e-mail today.

Wow! That is news. They want to call it FRAM.
...from the link above:

Nantero NRAM technology is based on carbon nanotubes and allows for non-volatile memory with high density and random access.

Elsewhere FRAM is defined:

1) Short for Ferroelectric Random Access Memory, a type of non-volatile memory developed by Ramtron International Corporation. FRAM combines the access speed of DRAM and SRAM with the non-volatility of ROM. Because of its high speed, it is replacing EEPROM in many devices. The term FRAM itself is a trademark of Ramtron.

This might be related:
https://en.wikipedia.org/wiki/Nano-RAM

Nano-RAM is a proprietary computer memory technology from the company Nantero. It is a type of nonvolatile random access memory based on the position of carbon nanotubes deposited on a chip-like substrate. In theory, the small size of the nanotubes allows for very high density memories. Nantero also refers to it as NRAM.

So, the idea is not new. If they pull it off and it does well, that will be a new thing.
(Note that FRAM is a trademark.)

But how does it actually work? In other words, how do the nanotubes move? Is this not a true solid-state system with no moving parts? Does not movement cause heat and wear? Just curious here.
