The Magnetic Racetrack Memory Project is in development by IBM’s Almaden Research Center. Informally called racetrack memory
(RM), it is a non-volatile memory
device that offers a storage density higher than solid-state
memory devices with a higher read/write
performance. The design is a racetrack concept where RM memory moves magnetic bits along nanoscopic “racetracks.” Racetrack memory may be seen abbreviated as RM.
