IBM develops new memory that holds 100 times more data than current memory

Thanks to IBM scientists—who says Intel does all the heavy lifting these days?—we may soon have portable devices that can hold more than 100 times more data than they currently do. The comparison that’s been thrown around is, imagine an iPod with a 500,000 song capacity. (The iPod classic holds 40,000 songs.) Nirvana, I agree. IBM’s calling the new type of memory “racetrack,” which works, in so far as it can be plained to non-physicists, by using the spin of an atom. Oh.

What’s even better about racetrack is that, while, like Flash, it has no moving parts, it can write and re-write without flaking out, unlike Flash, which can only withstand but so many re-writes before failing.

Akkor most memóriáról vagy háttértárról van szó?

A new digital storage technology will pave the way for MP3 players and other gadgets to store a hundred times more information. Like flash memory - the most advanced type of memory for small devices such as mobile phones - it has no moving parts, meaning that the problems associated with mechanical reliability are dramatically reduced.

Mi a kulonbseg? Tobbek kozt a sebesseg, es az, hogy megtartja-e az informaciot kikapcsolas utan is, vagy sem (volatile). Ha megtartja, akkor hasznalhato hattertarnak is. Ha nem, akkor csak operativ tarnak (memoria). A flash-t is lehetne memorianak hasznalni, csak ugye a korlatozott irasszam miatt nem celszeru (meg ugye valamivel lassabban irhato a ma hasznalt RAM-hoz kepest).
