Abstract
Racetrack memory units and methods for writing include a racetrack memory medium; a heat source/sink configured to change temperature according to an applied current; and a magnon source material in contact with the racetrack memory medium and the heat source/sink, such that a temperature of the heat source/sink causes a magnon flow in the magnon source material that injects a domain wall in the racetrack memory medium.
Claims8
A racetrack memory unit, comprising:
- a racetrack memory medium;
- a magnonic source material in contact with the racetrack memory medium, wherein a temperature of the heat source/sink causes a magnon flow in the magnon source material that injects a domain wall in the racetrack memory medium;
- and
- a heat source/sink, in contact with the magnonic material, configured to change temperature according to an applied current.
