ABSTRACT:
A magnetic racetrack memory device includes; a magnetic track having a plurality of magnetic domains partitioned by at least one magnetic domain wall, a current source applying current to the magnetic track sufficient to move the at least one magnetic domain wall and the plurality of magnetic domains along the magnetic track, a writing device disposed at a first location along the magnetic track and storing write data to the magnetic domains, a reading device disposed at a second location along the magnetic track and retrieving read data from the magnetic domains, and a write-back loop connecting the reading device and the writing device and communicating read data obtained by the reading device to the writing device.
