Texas A&M Research Brings Racetrack Memory a Bit Closer 55

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."

    Actually, the predicted speeds for racetrack memory are rather close to RAM speeds. It could be possible to operate it as primary storage - it would be a bit sluggish for calculations, but it would eliminate the need to read in chunks of files to be operated on. Given the increasing size of L3 cache, it could be possible for racetrack memory to replace SSDs and RAM while pushing hard drives into the "long-term storage" role, and have the L3 cache take the role of RAM.

    This isn't a firm prediction - I'm not even sure racetrack memory will come to anything, but if it does, "the death of RAM" is entirely possible.
