Abstract
The present invention relates to a Racetrack (RT) memory device that includes a racetrack layer and at least one reading element, in which the reading element includes a polarity-reversible Josephson supercurrent diode (=JJ). The polarity-reversible Josephson supercurrent diode is capable of detecting magnetic domains and thus magnetic domain walls in the racetrack.
