1. Inject electrons
The spin injector comprises two metals, one of which is magnetic, separated by an ultra-thin insulator. Apply a voltage between the two metals, and the electrons tunnel from the non-magnetic metal to the magnetic one.
2. Filter
The electron continues only if the spin matches the direction of the magnetic material. If the alignment doesn’t match, the electron will “scatter.”
3. Travel through the silicon
Electrons travel 350 microns through silicon while maintaining aligned spins—crucial because electrons need to travel between intrachip devices.
4. Detect 1s and 0s
Electrons are pushed out through a thin film of magnetic metal like a ski jumper. If the electron’s spin direction matches the magnetization of the film, it will land on a nearby semiconductor, where its charge is detected (say, a “1”). Mismatched electrons are
shunted elsewhere (a “0”).

AWSOME!!!!!!!!!!!!!!!!
ive always wondered why computers had to load
It seems like we should be able to do Trinary computations with electron-spin. Either no electron, up electron, or down electron.
Is this possible? Or would it be too difficult to change all of our computer infrastructure to accommodate trinary processing? Or would it be just slow us down because we'd have to convert everything back down to binary?
I don't think trinary computations are out of the question, they're just a little ahead of us right now. In order to perform trinary operations, we would have to completely rewrite machine code to take advantage of this advancement. Til then, best to stick with binary.
This isn't the first time I've heard of memristors, but I still get excited when I think about the prospect of "save state" for my computer :D
Now all we need is a genius scientist to develope a process for replacing slow, cumbersome electrons with shiny new photons! Then we'll be in super-duper computer business.
But will it ever be fast enough to keep up with
my furious jackin'? FilthyRichmond.com
Wouldn't be possible to do completely analog computations using memristers? I remember reading that they can store analog data. Instead of binary we could use trinary or even decimal or hex computations. Of course, this would be difficult and I haven't a clue of how we would make the switch.
This is more an improvement of memory vs CPU power though CPUs have been powerful enough for what most people do for a long time and good thing too since they have not improved no where near as much during the past 8 years as they have during the past 8 years before that.
But memory and storage have been a bottle neck since the P2/G3 days.
I also wonder how well do these memritors handle radiation since they deal with electron spin?
Radiation is everywhere from stray neutrons from decay of naturally occurring radio isotopes and cosmic rays.
This could effect off data retention times while they are powered off.
i really hope that they overcome the hurdles that come with a new product such as that
it would be pretty sweet to have a computer that would boot instantly (raising the amount of time that i can waist on the computer quite a bit :P)
and i think trinary computing would open a world of possibilities, it would be amazing if trinary was made backwards compatible allowing everything to work

Our technology will only be as good as our minds and you can only go so far as size,power,weight,speed and all the other attributes of a computer.
And what about those computers that have caught on fire because of overheating?Could these turn into ticking time bombs?

ha my computer just caught on fire yesterday
Lol, i rest my case!

THIS IS THE MOST IRRESPONSIBLE ARTICLE I HAVE EVER SEEN. IT SHOULD BE TAKEN DOWN. PLEASE, DON'T SHOW PEOPLE HOW TO DO THIS. THEY WILL GET CATARACTS IF THEY TRY IT.
THE POPPING VIDEOS ARE GENERALLY DONE BY SOMEONE DROPPING THE POPPED CORN FROM ABOVE.
guess who i am!
I didn't see anything irresponsible in this article. It's quite clear that computers will only continue to get faster. This is a good thing as far as productivity goes, but it's terrible for our already dwindling attention spans. I would like to see more compatibility between computers. http://www.rentex.com
