Texas A&M Research Brings Racetrack Memory a Bit Closer

MojoKid writes "IBM is one of a number of companies working on a next-generation storage memory project and a recent discovery at Texas A&M University is a step forward for the company's racetrack memory. Racetrack memory relies on a nanowire arranged perpendicular to the chip. Current pulses across the nanowires allow data to be shifted as necessary. In theory, racetrack memory could be the Holy Grail of storage, capable of replacing both traditional hard drives and SSDs simultaneously. Racetrack memory could solve multiple problems and commercial implementations could offer hard drive-level density. Performance and reliability would both be far superior to today's SSDs. To date, IBM has demo'd a three-bit racetrack configuration. It's a start, but it's far from a shippable product at this juncture." What the A&M researchers have come up with is "a way to pulse the current much more efficiently and quickly."

You must've clicked through to the original article, where that's been modded up quite a bit :)

But yes. It has similarities. The main difference as far as I can see is that this is much more '3D'. I sort of imagine a carpet waving around (funny mental image, do we now need tiny kittens to scratch their nails on that?)

But the option of being able to store multiple bits no a relatively small footprint is of course the most interesting one, although I wonder about the heat dissipation or production of these sort of arrays..

(And yes, it looks like you were a first :)

A more important difference is that the old delay lines had the bits constantly moving along - when you wanted to access one, you just waited for it to pass by the transducer. This model has the bits hold still until they are made to move back or forth along their track, like a train moving one-carriage-at-a-time past a loading crane.

That's nothing! Your post has exact copies of everything you cited.

But yeah, Slashdot summaries these days are almost always just copy-and-paste from the article.
