Anti-static Polymer Stores Data, Too 116

Posted by CowboyNeal from the super-plastics dept.
Tau Zero writes "The BBC reports that a group of scientists (including Stephen Forrest) have discovered a new use for the anti-static plastic film polyethylenedioxythiophene: storing up to a gigabyte per cubic centimeter. The storage technology resembles an old fuse-link PROM; a bit of polymer between two electrodes conducts electricity when new, but a strong pulse turns it into an open circuit. The polymer is already cheap, and read/write speeds are claimed to be good. The researchers predict that this could be made into working devices in a few years (no word on whether this means devices in the laboratory or retail packages)." Update: 11/29 16:34 GMT by CN : Whoops, we already reported this earlier, and I was fooled into thinking it new by the BBC. Given the slump of news due to the holiday weekend, it's still worth mulling over, though.

      Interesting analogy considering the state of the industry at the moment. Intel is working on a replacement for flash [ebnonline.com] that utilizes chalcogenide - the material used in rewritable disks like CDRW and DVDRW.

      The idea is the same as what we have here except, instead of the "blown fuse" technique, the chalcogenide material stores data as a level of resistance (which can be set/reset trillions of times). Intel believes that this is a successor to flash, which is expected to hit the scalable wall at 45nm (2007-8ish). Because the chalcogenide material can be "programmed" to hundreds of unique levels of resistance, it is expected that Intel will get as much as 8 bits per cell, which will put density into or above that of conventional hard drives.

      So there you have it - DRAM and hard drive replacement in one.

      If you are looking for an investment that leverages this technology, consider Energy Conversion Devices [ovonics.com] out of Rochester, Michigan. The CEO is Stanford Ovshinsky of "Ovshinsky Effect" fame. They invented this technology back in the 60s and Gordon Moore even wrote a paper on it in 1970, I believe. But material technology is only just now beginning to develop to the point that this can become feasible.

      Disclaimer - I am an investor in this company and I consider it EXTREMELY high-risk. The company is currently teetering on the edge of solvency.

          Google for this. Intel is throwing the weight of their R&D to OUM because it is so process-friendly. They are currently running OUM alongside the Pentium 3.0Ghz line (not commercially viable / internal R&D use only).

          A brief here... [intel.com]

          Ovonyx non-volatile memory technology offers significantly faster write and erase speeds and higher cycling endurance than conventional Flash memory. It also has the advantage of a simple fabrication process, which allows the design of semiconductor chips with embedded non-volatile memory using only a few additional mask steps.

          Interesting comments from the horse's mouth.

          -Intel is also investing in competing technologies

          Yes - but they are on record (see original EBN link from parent post) stating that OUM shows the most promise. But, as I did state earlier, I see this as extremely speculative. I would not be here if I was not a whore for the technology. I fully expect to do one of two things with my investment:

          1) 100 fold return by 2010

          That is what speculation is all about.

      Plan 9 in particular uses WORM media for long term storage and as a form of versioning - it uses magnetic rotating disk platters for level-2 caching and volatile RAM for level-1 caching.

      From http://plan9.bell-labs.com/sys/doc/9.html :
      "The file server has three levels of storage. The central server in our installation has about 100 megabytes of memory buffers, 27 gigabytes of magnetic disks, and 350 gigabytes of bulk storage in a write-once-read-many (WORM) jukebox. The disk is a cache for the WORM and the memory is a cache for the disk; each is much faster, and sees about an order of magnitude more traffic, than the level it caches. The addressable data in the file system can be larger than the size of the magnetic disks, because they are only a cache; our main file server has about 40 gigabytes of active storage.

      The most unusual feature of the file server comes from its use of a WORM device for stable storage. Every morning at 5 o'clock, a dump of the file system occurs automatically. The file system is frozen and all blocks modified since the last dump are queued to be written to the WORM. Once the blocks are queued, service is restored and the read-only root of the dumped file system appears in a hierarchy of all dumps ever taken, named by its date. For example, the directory /n/dump/1995/0315 is the root directory of an image of the file system as it appeared in the early morning of March 15, 1995. It takes a few minutes to queue the blocks, but the process to copy blocks to the WORM, which runs in the background, may take hours.

      There are two ways the dump file system is used. The first is by the users themselves, who can browse the dump file system directly or attach pieces of it to their name space. For example, to track down a bug, it is straightforward to try the compiler from three months ago or to link a program with yesterday's library. With daily snapshots of all files, it is easy to find when a particular change was made or what changes were made on a particular date. People feel free to make large speculative changes to files in the knowledge that they can be backed out with a single copy command. There is no backup system as such; instead, because the dump is in the file name space, backup problems can be solved with standard tools such as cp, ls, grep, and diff.

      The other (very rare) use is complete system backup. In the event of disaster, the active file system can be initialized from any dump by clearing the disk cache and setting the root of the active file system to be a copy of the dumped root. Although easy to do, this is not to be taken lightly: besides losing any change made after the date of the dump, this recovery method results in a very slow system. The cache must be reloaded from WORM, which is much slower than magnetic disks. The file system takes a few days to reload the working set and regain its full performance.

      Access permissions of files in the dump are the same as they were when the dump was made. Normal utilities have normal permissions in the dump without any special arrangement. The dump file system is read-only, though, which means that files in the dump cannot be written regardless of their permission bits; in fact, since directories are part of the read-only structure, even the permissions cannot be changed.

      Once a file is written to WORM, it cannot be removed, so our users never see ``please clean up your files'' messages and there is no df command. We regard the WORM jukebox as an unlimited resource. The only issue is how long it will take to fill. Our WORM has served a community of about 50 users for five years and has absorbed daily dumps, consuming a total of 65% of the storage in the jukebox. In that time, the manufacturer has improved the technology, doubling the capacity of the individual disks. If we were to upgrade to the new media, we would have more free space than in the original empty jukebox. Technology has created storage faster than we can use it. "

    I think the fast development of larger and larger data storage containers is actually a very bad thing for society. It causes much more problems than it creates benefits. Let me list some of the basic problems:
    1. Increased storage capacity lead to a decrease of data quality which renders aquired data in the long term basically useless. You might have 100s of pentabytes of data, you'll never have the time and processing power to analyse it or make any sensible use of it.
    2. Increased storage capacity lead automatically to the storage of more data. The storage limits are just reached much faster and you'll be basically again stuck at the storage limits. But this time point 1. kicks in and you have more storage units but much less use for it.
    3. The increased data storage increases the propability of the violation of personal and cooperate privacy by goverment or other 3rd parties. Combined with the automatic effect of point 2. this can lead to an Orwellian society if high storage adaption if faster than the adaption of society - even if the political leaders don't aim for it initially.
    4. Increased data storage makes backup and other storage presevering operation more expensive. This results in lower preserving operations per important data units which results in high loss propabilities. I think I don't have to point out the further consequences.
    At the whole the whole dedication to increasing data storage is in fact a bad thing. Instead we should concentrate our economical forces the enhance data quality which is a more important and harder task. Note further that data storage and data care is basically a low-skilled and personal intensive operation. Such operations can be easily outsourced by high capacity communications channels like the internet to developing countries like India, China or Poland. These techniques have no future in high wage countries like US, Japan or Europe. So a dedication the high-skilled data quality enhanching would make much more sense from an economical point of view.

      I don't believe more data storage may or may not be a bad thing. Although you write that "in fact" it's bad, actually this is your opinion, not an established fact, and certainly not a point of consensus among people who are intimately familiar with the common points you raise.

      More storage capacity can create some problems, and the ones you describe are among them. It also solves some problems, among which are problems that have held back basic scientific and medical research, as well as other fields that some people consider useful.

      Just to address a few points:

      Increased storage capacity can lead to a decrease in average data quality, not the total amount of quality data. So this only renders data useless if you have no way of finding just the data you want, or if you feel obligated to use all of it. In the rare cases that meet these criteria, having smaller storage doesn't solve the problem, it just makes the problem logically impossible to solve rather than logistically (because the data are gone, not just hard to find).

      I find the argument that data will continue to grow fast enough to fill available storage unconvincing. The amount of storage I have now is much more than I had 20 years ago. Just like 20 years ago, I could probably use more disk space, so you're right in that sense. But I'm able to do many more things with that disk space now, like storing music, video, and data for my research. It's not that the same things I was doing before are now taking up more space. It's that the bigger disks I have now have made it possible to store much more of the data I would like to keep. Sure, digital pictures and movies keep sucking up more space. But that's a huge benefit of bigger storage. Right now I'm throwing away a lot of data I'd rather keep, in part because of storage (and in part because my current cameras have sensors that aren't up to it). I really do want these data, and bigger storage is critical to making it possible for me to keep them. The amount of storage I have could easily grow by two or three orders of magnitude without making it the least bit more difficult for me to index my data.

      Lastly, I doubt that data storage is the limiting factor in shepherding us towards an Orwellian future. A few gigabytes of storage for everyone in this country seems like a good start. Mining that data will be difficult. Yet I doubt the mining difficulties are seen by the relevant people as a reason why more storage would be bad.

      In short, I agree that dealing with large amounts of data can be difficult in some cases. I don't agree that it's bad for society.

    I never expected to see a development like this; as a sci-fi aficionado, it's quite interesting to see some of the other methods that have been highlighted both fictionally and in the news.

    As well as optical storage (which we already use with spinning discs CD/DVD) optical memory will be able to integrate into optical processors, such as the optical DSP that was recently announced in Israel.

    Would this plastic storage would be sensitive to magnetic damage like a traditional hard disk as well.

    Finally, I read that the Earths' magnetic field can 'flip' every 100,000 years and we're about due for another flip soon. This would cause tremendous damage to all magnetically stored data, as well as plenty of electrical equipment, as it is not a quick clean flip, but equivalent to a massive electromagnetic storm right under our feet - possibly lasting years according to archeological evidence.

      Hard disks do not last over geologic periods of time :) You are correct, it is not a quick clean flip...however, the amount of time it takes for these inversions to occur is considerably longer than the life of a hard drive.

      Why would a material whose properties depend on conductivity be affected by magnetic fields? C'mon, think before posting.

      If you can only scan it at the speed of rotating media, you're way too slow for even secondary storage.

      The flip of the poles is on-going, and has been going on for thousands of years. The pole-flip is to EMP (or anything else that might damage magnetic media) as the millimeter/year changes in sea level are to tsunamis.

          "Quickly", in geologic terms, is thousands of years. The measured rate of the decay of Earth's magnetic field is 0.07% per year [nasa.gov]. You should have known this before posting.

      It seems that they moved it from my old bookmark position. It's also come on quite a way since 1990.

    • Holographic memory turns out not to be a good match to today's computers: the data comes out too fast to be useful with current systems and writing takes too long.

      Optical computers have been used in some specialty applications (e.g., optical correlators), but they are not usually cost effective.

      As for a flip of the earth's magnetic field, that's probably not strong enough to damage any media, but it might result in higher radiation levels, with all sorts of unpleasant consequences.

    Don't be so hasty with putting this memory in your computres and MP3 players. The way from idea to stores is quite long and a lot of ideas don't go beyond the project stage.
    There still are Polymer Memory, Ovionics Unified Memory (OUM), Magnetoresistive RAM (MRAM) and ferro-electric RAM (FeRAM) [zdnet.co.uk] There is a lot of intresting memory-related projecs in progress, only time will show which of them are actually useful and will be installed in our future computers.

    Sounds theoretical.

    Theoretically, a 1-cm silicon memory chip stores way more than a GB per cc.

    But good luck stacking them at that density with any hope of reliability.

    Where do we get this so called fuse-link pr0n?
  • Nobody has ever mass produced a memory technology that wasn't relatively flat in shape. If a cubic centimeter can hold a gigabyte or 2^33 bits, a single layer can probably hold 2^(33*2/3) bits or 256 kb, not taking into account the shape of the cells. If they somehow manage to stack say, 32 layers of this, they'll get 8mb, which is much more realistic and still pretty good for a square centimeter of non-volatile memory.

One would be the size of a fat CD-case and work like a Zip disk. This would hold about 50cm3 = >50 GB. You'd carry one of them with you, and it'd be your life, until it runs out. For digital cameras and portable Vorbis players (this is the future, remember?), you'd have a smaller thing, like a CF card only with about a GB. A s

      False. Magnetic drum memory systems were mass produced from the 1950s through the 1970s. They were used as the main memory on a few computers (e.g., IBM 650), and as secondary store (e.g., swapping, paging, or for frequently accessed files) on many.
