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."
