Racetrack memory or domain-wall memory (DWM) is an experimental non-volatile memory device under development at IBM's Almaden Research Center by a team led by physicist Stuart Parkin.^[1] It is a current topic of active research at the Max Planck Institute of Microstructure Physics in Dr. Parkin's group. In early 2008, a 3-bit version was successfully demonstrated.^[2] If it were to be developed successfully, racetrack memory would offer storage density higher than comparable solid-state memory devices like flash memory.^{[citation needed]}
