    Magnetic Memory (RAM) will make rebooting obsolete

    Just read an interesting article on the development of magnetic RAM, which when completed will make rebooting PCs a thing of the past in just a few years: http://www.mytelus.com/news/article....icleID=1343531 I hate having to wait while my computer is dragged awake...this should be very useful.

    It sounds all spiffy. But I must say the concept of hyperram does sound somewhat better... can't wait either way.

    Actually it sounds a lot like the Magnetic Core Memories which were used in early computers between the time they stopped using tubes but before IC memory first became available.

    With those computers you could halt the processor, record the values in the registers then turn off the power. After you turned on the power again, you could restore the register values and start the processor running again like nothing had ever happened.

    Historical note, the computers in the Challenger Space Shuttle used Core memory, those memory modules were recovered from the ocean floor and Nasa read the contents of those memory cores. They didn't gain much in the way of useful data for the investigation, but it does testify to some of the value such memory could have. Columbia's computers were upgraded and used IC memory chips so that feat wasn't possible in the latest disaster.

    computer deal store get any windows OS and PC with free magnetic ram.

    (1) that you will be persuaded by me(in a legitimate mannor)
    (2)It is worthless to you, when i have finished

    Sounds good, but ram is all about performance, if it can operate at a high frequency and low latency then bring it on. Otherwise I'm afraid it'll not become mainstream, particularly since high bandwidth fsb's are becoming more prevailent.

    Possible use for this... get rid of the battery on the BIOS chip, using the magnetic RAM instead. Then, if they do take it that far, maybe eventually have the entire OS operate out of the magnetic memory, essential programs too, and make hard drives obsolete. Maybe a little far-fetched, but think about the potential. I've been hearing these ideas from hardware geeks for the last 5 years.

    wave a magnet over it? or de magnatise it? in a carefully conrolled manor.

    I would imagine you remove something from it by writing something else in it's place. This may end up going the route of "bubble memory", an interesting technology but ultimately a failure, it turned out to be too slow to keep up with the faster processors. OTOH, the core memory I mentioned above was faster than the IC memory which ultimately replaced it though the IC memory eventually made up and then exceeded that speed difference. The IC memory did manage to replace the core memory while it was still slower, it was just so much cheaper to produce and maintain that the slower speed was worth working around.

    I also remember people looking at the 16K chips and saying that the ultimate memory density had been reached. It was talk like that which was one of the original driving forces behind the development of the bubble memory.

    The possablities for magnetics have been around for a long time, however people always tend to avoid them like the plauge.

    3 1/2 inch flopies were out-dated by the CD, then that was outdated by "ZipDisks", however, ever since the 'CD Go train' everyone has jumped into they no longer wish to change to a better system (neither do I).

    But the reason for it is the same reason people use Microsoft, everyone else uses it. It becomes very chaotic when changing from one format to another, even if it is outdated. Some (most?) web sites will not get on the new PHP that is comming out because it doesn't use MySQL, they plan on SQLite (a much faster SQL), yet just about no one will re-program to fit the new PHP because they don't think its worth the effort (is it really?).

    The ZipDisks hold far more information then any CD, and the CD makers have recently made about a 200 MB jump upwards in storage while it still lacks far behind the most recent magnetic storage disks.

    This new "Magnetic RAM" will be the most logical step in the feild of putting people back onto the "Magnetic Train" that anyone has come up with to date. It will [more then likely, the article gives me a 404, so I can't check] not bother many people, be compliant with regular existing cards, and proably make a few advances in super computers.

    CDs were not outdated by Zip disks, the Zip disk was simply too small and with todays huge disk drives and huge programs even CDs are on the small side. Also going against the Zip disks were the fact that IoMega made them which meant they were low quality.

    Appearantly, MRAM is due to be released sometime in 2004.
