Diamonds Used To Increase Density, Performance of Phase-Change Memory

Posted by timothy on from the ok-start-counting-down-to-5-years dept.

Lucas123 writes "Researchers at Johns Hopkins University have shown they can increase the density, performance and the durability of phase-change memory (PSM) by using diamonds to change the base alloy material. Instead of using the more typical method of applying heat to the alloy to change its state from amorphous to crystalline, thereby laying down bits in the material, the researchers used pressure from diamond-tipped tools. Using pressure versus heat allowed them to slow down the change in order to produce many varying states allowing more data to be stored on the alloy. 'This phase-change memory is more stable than the material used in current flash drives. It works 100 times faster and is rewritable millions of times,' said the study's lead author, Ming Xu, a doctoral student at the Whiting School of Engineering at Johns Hopkins University. 'Within about five years, it could also be used to replace hard drives in computers and give them more memory.'"

    It's 100% true. I use Gamemaker, and I'm proud of it! In fact, everyone who doesn't is simply a disgrace. All True Programmers use Gamemaker.

    Return, return, return, return, return to Gamemakerdooooooooooooom!

      It cannot be said that your words are false. Unfortunately, this is among the greatest of inconvenient truths for some closed-minded imbeciles.

      I'll return to Gamemakerdom right this minuteness.

      I agree, gamemaker is great. Just imagine a world without gamemaker. A world without it would be just like the dark ages. Everyone, return to gamemakerdom today!

      WTF? Is this supposed to be funny, or are you and your two buddies just shills for Gamemaker?

      Why you little wusaaaaaaaaaaaaaaaaaaaaaaaaaaaaaay!

      True Programmers use Gamemaker. You're nothin' if you say otherwise. Use Gamemaker. Only use Gamemaker. You're a Gamemakerless ultimatum!

    Way off topic but I have to say... you have the dumbest signature I've ever seen "Friendly Reminder: Apple, Google, Nintendo and Valve are the for-profit corporations a Slashdotter is permitted to like." I guess we can't like RedHat? Or github? MongoHQ? Sourceforge? Geeknet? Need I go on?

    I read /. uncensored for the trolls and such. Usually there's some larfs
    Perhaps, not today.
