IBM is working on a new type of memory that combines the speed and efficiency of flash with the capacity and low cost of hard drives.To wit, "Racetrack" won't see the light of day for perhaps another decade, though researchers say they could have a prototype ready in four years. Explains IBM fellow Stuart Parkin: Racetrack memory stores information in thousands of atoms in magnetic nanowires. Without the atoms moving, an electrical charge causes data to move swiftly along a U-shaped pipe that allows data to be read and written in less than a nanosecond.
Racetrack memory will also require far less power and generate far less heat, meaning that battery-operated devices could run for weeks on a single charge and last for decades.
Parkin expects Racetrack to be inexpensive to manufacture since fewer transistors will be required and each memory chip will hold thousands of nanowires in a small footprint.PC World, The Inquirer
