RM - future of memory storage?

[Aury]

RM - racetrack memory: a form of magnetic, non-volatile memory storage that relys on "sliding" magnetic domains along nanowires. Each magnetic domain contains a 1 or 0 state, and can be "moved" via electric current in the nanowire. By making a folded nanowire, then stacking a bunch of these folded wires next to each other like books, a storage density of far above conventional HDD's can be achieved. Meanwhile, even plain horizantal setups can outcompete current flash memory. What is even better is that RM does not have any truly moving parts (despite the fact that you get a movement of 150m/s (converted from 150nm/ns) from RM which is millions of times faster than a HDD), thus eliminating mechanical failure (like HDDs), and it does not "wear out" like flash memory does after about 10-20 thousand read/write cycles.

Wolfy, have you ever read about memristors? If not, then please visit this link: http://www.spectrum.ieee.org/semiconduc ... -memristor

The article describes a breakthrough in memory technology: "the missing fourth circut" or so the article calls it. Anyhow, please read, and let me know what you think on the subject.

Yep. I thought though that was having memory density issues by comparison to current flash memory systems...

what about Z-RAM and TTRAM ?

In theory Z-RAM, when in large scale production, should be less expensive and higher density than current ram technologies.
