RESULTS: Researchers at IBM made a novel type of memory, known as racetrack memory, by means of inexpensive manufacturing processes used to make conventional computer chips.WHY IT MATTERS: The basic design of racetrack memory, which stores information on nanowires, was first proved feasible in 2009. The technology has the potential to store data faster than hard disk drives and to store thousands of times more data in a given space (see TRIO, March/ April 2009). The early prototypes, however, were made using specialized lab processes that are impractical for mass production.
