Carbon Nanotube-Based NVRAM In 2-3 Years? 66
According to NanoWerk, UC Riverside researchers have come up with a memory device based on telescoping multi-walled carbon nanotubes. According to one of the researchers, 'This finding leads to a promising potential to build ultrafast high-density nonvolatile memory, up to 100 gigahertz or into the terahertz range" and a prototype could be demonstrated "in the next two to three years.' Similar devices from UCLA and Caltech based on bistable rotaxanes are farther along in being integrated into actual memory circuits, but tend to break after a fairly small number of position changes. Carbon nanotubes may promise more durable switches.

But it is still a good news to know that there is something coming for NVRAM better than flash memory

"The ENIAC was controlled through a train of electronic pulses."
--and--
"because the various units of the ENIAC could operate simultaneously, the ENIAC could perform calculations in parallel. (BUT!) ENIAC programmers tended to avoid this use because the impressive but limited reliability of the ENIAC favored the use of as few units as possible for a given application."
