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"!

I wonder how long it'll be before the *AA asks for a tax on atoms "to offset the costs of piracy".
Oh man are those guys gonna be pissed.

Only half joking: Researchers at U.Michigan hope to
store up to 10 bits per atom, by using Rydberg states.

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).
Techie: Um, we've lost the corporate file server.
Boss: You mean it crashed?
Techie: No, it's working fine. We just can't find it.
At the bottom of the story, a key factoid: "Timeline: > 20 years" Holographic memory at 1 TB/cc will give this technique a run for its money on density and will probably be ready first.
Now, if I could only do it!!!
All your favorite sites in one place!
Also, you could store the contents of:
149 200GB Fluid Bearing WD HDDs
45850 CDs
116400 256MB Flash Memory Cards
298000 Zip Disks
931300 32MB Memory Sticks
OR!!! 20696000 1.44MB Floppies
No offence guys, but come on. Post meaningful figures.
Its actually 250 trillion bits per square inch.
28.42 TB per square inch.
Now thats impressive.

equivalent to storing the contents of 7,800 DVDs in one square inch of material ...how much data could be fitter in one *cubic* inch!

First off, if this is widely used, won't this

A small fraction of a cents in gold per 1000 terabytes. Your computer already has much more gold in it than one of these would require.
I realize that these are gold MOLECULES,

Um, a 320 kilobits per second .wav would sound like crap.
CD audio is 44,100 samples per second per channel. Each sample is 16 bits and there are 2 channels.
That works out to 1411200 bits per second, or just over 1378 kbps.
Anyway, after working with 96kHz/24bit/multitrack studio equipment CDs sound like crap too. Which is what DVD-A is pretty close to. I think Vorbis streams have support for higher sampling rates, greater bit depth, and >2 channels.
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
I dunno. I measure everything in football fields.
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. :)
It's sure as hell better than to use a gigantic "Laser" to get lots of money.

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?
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.
I use furlongs myself.
How many furlongs in a pennyweight again?
Nuts, I guess the original poster should have linked to a conversion site, huh?
Robots are everywhere, and they eat old people's medicine for fuel.
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.
*Condense fact from the vapor of nuance*
I'm curious; let's do the math:
Atomic weight of Gold: ~197
Price of Gold: $300 per ounce = $10.70 per gram
Atoms per gram: 6.02e+23 / 197 = 3e+21
Price per atom: $10.70/3e+21 = 3.57e-21 cents
Price per Terabyte: 1/357000 cent
This conclusively proves that the vast majority of the $100 you might pay for a 1-terabyte atomic storage unit goes to marketing overhead and sales commissions.

With such density, doesn't it become more subceptable to EMP (electro magnetic pulse), sun flares, hot coffee, etc.?

Great, my desk is already cluttered with all my computer stuff, scanners, printers, hubs, etc. Where am I going to find space for a scanning tunneling electron microscope?
what exactly do you mean by "rogue neutrinos"?
neutrinos are "little neutral things". they can travel through cubic light-years of *lead* before the probability of an interaction becomes close to one.
i don't think that you need to worry about the neutrinos.
(besides, how often have neutrinos wiped out the contents of your regular harddrive? not even i have had that sort of problem)

I suspect that we store the information necessary to do physical motions in a very lightweight format.

All digital music is compressed. The simple act of sampling and digitizing at some arbitrary frequency and bit depth is a form of compression. It's compression by omission.
Any TRUE audiophile would not be listening to digital audio, but instead would use high quality analog sources.
Article X: The powers not delegated... by the Constitution...are reserved...to the people
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.
