The technology promises to improve storage capacity of disk drives and the speed of memory chips. You might call it flash memory on steroids. Also, racetrack memory can be rewritten many more times than today’s flash memory. The technology, or something like it, is likely to make solid-state drives the workhorses of data-center storage rather than just premium, high-performance alternatives to hard disk drives.http://www.wired.com/wiredenterprise/2011/12/ibm-racetrack/
Racetrack memory isn’t the only game in town. IBM, Micron Technologies, and Samsung are among the companies working on phase-change memory. This PRAM stores data by switching microscopic regions of a memory chip between crystalline and glass-like states, which have different levels of electrical resistance.http://www.wired.com/wiredenterprise/2011/12/ibm-racetrack/
Muistiteknologia etenee kovaa vauhtia. Racetrack muisti perustuu nanoteknologiaan ja spintroniikkaan (spintronics).
