IBM Creates Working "Racetrack Memory"

Posted by kdawson on from the and-they're-off dept.

holy_calamity writes "IBM has created the first working 'racetrack memory' device — a technology we've discussed as it's been touted as the future of memory. It works by writing bits using the magnetic domains inside a very thin wire. Those domain can be shunted along this 'racetrack' and past read heads."

    I can't be the first one to read this and think, eh, isn't this just bubble memory?

    Oh! New motherboards would have to be introduced! That could take some time to switch to indeed, because it's quite rare that such a thing happens.

    Except for the switch from DRAM to SDRAM. And the switch from SDRAM to DDR, and from DDR to DDR2, and from DDR2 to DDR3, and from AGP to PCI-e, and from IDE to SATA, and.. and.. ad infinitum.
