1. A method of forming a memory device comprising magnetic tracks individually comprising a plurality of magnetic domains having domain walls, comprising:

  • forming alternating elevationally outer regions of two different composition materials;

    removing one of the two different composition materials inwardly to an elevationally outermost location of the one material that is deeper than an elevationally outermost location of the other of the two different composition materials at the end of said removing to form alternating regions of elevational depressions and elevational protrusions; and

    forming a plurality of magnetic tracks over and which angle relative to the alternating regions, interfaces of immediately adjacent of the regions individually comprising a domain wall pinning site in individual of the magnetic tracks.
