Atomic Scale Memory
maddugan writes "Technology Research News is reporting that researchers from the University of Wisconsin at Madison have put the theoretical to the test by using single silicon atoms to represent the 1s and 0s of computing. This is equivalent to storing the contents of 7,800 DVDs in one square inch of material."
I predict 20 posts joking about how this memory will improve the performance of the next version of Windows, or being just barely enough for the next version of Windows.
I'll only need 5 drawers for my Pr0n collection now!
Code, Hardware, stuff like that.
Gives a whole new meaning to the term "atomic transactions"!

More storage space than I know what to do with, for this week at least.
This isn't actually very useful : what we want is atomic scale logic gates, not data storage. In fact I'd venture to say that this technology is NOT what we will be using in the future for extremely dense memory. Why? Because its 2 dimensional and requires an independent readout head (that is MECHANICAL). Making it work anywhere but a vacuum may be impossible. (though that is not a real problem : making a disk drive that has an internal vacuum is quite feasible) A solution that is thousands, even millions of times faster would be a system that reads itself : i.e. a 3 dimensional array of logic gates to form a molecular version of ram. In addition, you could cram far more bits per gram of material used for the media. (I can't say per square inch because that would be misleading) In addition, storage capacity is not what our computers need more of : its performance (especially in accessing all those gigs of storage).
RAM, Harddrives, or even many processors.
While I would hesitate to speculate on this kind of technology, if introduced, would mean an end to the way we think about storage and processing.

From what I gather in this article, this method uses the abscence or existance of gold molecules on a silicon surface to mimic the "1" and "0" of binary.
First off, if this is widely used, won't this be expensive? I realize that these are gold MOLECULES, not bricks, but how much gold would it take to put a cubic inch in every PC in America?
Secondly, I'm guessing that magnets won't mar these disks like they will current magnetic media. Granted, the drive will most likely have some magnetic parts, but perhaps this will make putting a subwoofer next to a computer case a little more safe. I realize that there's other stuff in a PC that can screw up if they come close to magnets, but at least if they screwed up I could take this meda and put it another machine without worrying about it being screwed as well.

This article [http://www.eetimes.com/at/news/OEG20020319S0029]
talks about using a cell matrix which configure their neighbours at run-time,
something like the game-of-life or a more generic turing machine sort of thing.
This has lot of applications, including a highly programmable FPGA which
is very simple to fabricate or even complicate circuiry.
What really attracted my attention was the passage at the end:
>Cell Matrix has been working with nanotechnology groups, hoping to forge a
>new computing substrate from some type of atomic-level fabrication technique.
>Macias was impressed with work at Hewlett-Packard Laboratories in which a
>matrix defined by erbium disilicide wires that address rotaxane molecules
>has been proposed as an atomic-level route to massively dense FPGAs.
Could this new research be an answer to these people ? Probably combining
the two technologies, not only do we have a massive memory-device, but
a massive computing device : Imagine an FPGA (or an ASIC) with a million
times more density!
DO NOT PANIC
Seeing as I currently attend UW-Madtown, this holds a special place in my heart... oh yeah, I'm in the Engineering Mechanics and Astronautics program, so that might have something to do with it too. Anyways, because I tend to remember cool stuff like this going on here at UW, I remembered another press release by us concerning Quantum computers. Yummy!
IWARS.
People, in general, disappoint me. Politicians even more so.
sure it's a lot, but this is the limit for some time to come... I guess I was just expecting more from something on atomic scale.
btw, 7,800, DVDs? come on, most people on here are literate, why not post some power of ten of bytes? btw, do I need to start with my explanation of how pointless measuring things in LoCs and HGs is yet, or wait till more of those are posted? (every damn time that storage comes up)
on the other hand, this is a lot of space... guess pretty soon I'll just have discs labeled "Music", "Video", "Software" where the title does in fact mean all music that exists :) just don't tell [RI|MP]AA (actually, can we just call the RiMpa from now on? kind of has a nice ring to it)

In 1959 Richard Feynman said that all the information accumulated in all the books in the world could theoretically fit in a cube 1/200th of an inch on a side.
You can read the transcipt of the speech from when he made that prediction.
Feynman worked on developing the atomic bomb, he won a nobel in physics and is known as much for his scientific research as for his story telling.

When DVDs are burned and read, you don't simply read raw data off. The information is, of course, encoded. The DVD (and CD for that matter) specification says to use Reed-Solmon encoding. Saving the long math, RS encoding is about the most advanced error-correcting scheme that can be implemented in low-cost hardware today. By encoding data this way, your DVD (or CD) can become fairly scratched, but still play. RS protects against multiple-point errors. However, there is a price to pay - for every ~33k byte block on a DVD, almost 5K bytes are used in the parity checks for the DVD. See this file for more gritty details about DVDs. This means your 4.7GB DVD really holds about 5.48 GB of raw data.
Now, why is this relevant? Harddrives use their own error correcting schemes too. Manufacturers have the luxury of creating their own encoding systems since they're the ones that provide the read/write mechanisms. You can't pull the platter out of one harddrive and stick it in another. Hard drives typically use CRC (cyclic redundancy check) encoding schemes. I know you have all gotten CRC errors on a floppy way back when - that's what it stands for. Anyway, CRC is much less efficent when you compare the protected data to parity information ratios. While I wasn't able to pull the actual numbers from the Internet or my old math books, you can find a discussion and sample math here.
When you boil it down and relate all this information to our magical harddrive, the maximum usable density of the data would hover between 85%, or 6630 DVDs/in^2, to 60%, a measly 4680 DVDs/in^2, of the listed capacity. This is all assuming that the ideal lab conditions are maintained for a consumer level product.
As always, beware what the numbers tell you. However, if this can fly, then it would be an awesome step forward. Once you get Windows 2010 installed, you might even have a few Gig to play around with!
Considering I don't store much money in my bank account, I sure as hell would risk my account being drained from $10 -> $0 along with the equal risk that its value will go from $10 -> 3.3E23 dollars. :)

That was funny :). If I ever got a chance to moderate, you'd get +1 funny :)
What's the point in having such amazing densities? If all the material one would want to put on such a data storage device is locked up in some legal way, what's the point?
Also if such a device comes to the market who needs compression? Imagine a non-compressed film at full academy resolution 2.35:1 aspect ratio, 3656x3112 pixels scanned at 4k. Of course we would need a display that could play back such a resolution. There is the IBM T221 (3840x2400)16:10 aspect ratio monitor but it only does 41hz. I would want at least 60hz refresh rate. Also music would no longer need to be compressed, I hate MP3 anyways. Hasn't anyone heard of sound quality? The quality of mp3 sucks. Give me uncompressed anyday.
See http://uw.physics.wisc.edu/~himpsel/nano.html, or this and Feynman's talk on the subject.

It seems to me that over the past several years lots of research has been done on possible storage medium, yet the basic PC storage structure has yet to change. I remember reading on /. where someone figured out how to get 10 gig on a roll of scotch tape, but I still have magnetic drives. Do you have rolls of scotch tape in your machine?
When and where can I buy some! How about some economies of scale too, so I can buy some and still get a car.
Seeing as this is still basically proof of concept, and I previously thought it was possible, I'm not all that impressed.
CDROMs use a large amount of raw data doing the same thing. A "700mb" CDROM actually holds around 805mb or so, but when used as a data cd that extra 100 goes to error checking.
What is amazing is not the part about the data density, but the part about the way this memory is written. It is done by adding and removing individual groups of atoms. This means that, unlike today's hard drives, it should be possible to completely and totally delete data from the medium.

Still, he trusts the magnetic orientation of a metal disk or metallic tape. However, a concern would be if some of the atoms happened to be radioactive, so the gold and silicon would have to be processed very carefully to ensure that none of the atoms are unstable.

Any bets as to how long it will be before some lab announces they use atoms to store entire bytes?
Their announcement will tell us that instead of that "old-fasioned moving of atoms" to represent 1s and 0s, the new technique changes the electron (or proton) count of an atom to represent up to one full byte of information in the same space.
Hmm.... what elements are stable enough at that many charge levels to do such a thing?
I do find it interesting that the access speeds and density of new memory technologies seem to be inversly proportional (and then some). We could probably write to a whole room full of conventional memory in the time it would take to full up a few bytes of this room-sized new memory.

Feynman's "Plenty of Room at the Bottom" speech is deservedly famous, but the earliest discussion I can think of of the absolute limits of information storage is in Robert Heinlein's 1951 novel, Between Planets , where the Venerians' secret plans are encoded on a tiny "message wire," hidden in a ring. The human protagonist is surprised that so much can be stored in such a small object, and some passing comment is made about the possibilities of atomic information storage. I think.
And, for that matter, the tiny mechanical hands described in Feynman's speech are very much like the "waldoes" in Heinlein's story, "Waldo" (1942).
Depends on the size of the lenses :-) We'll just need some photons here and there to reconstruct the thing. We'll be so advanced by that time. We can even have nanotech robots chasing the right photons :)
