Abstract
A method of forming a memory device having magnetic tracks individually comprising a plurality of magnetic domains having domain walls, includes forming an elevationally outer substrate material of uniform chemical composition. The uniform composition material is partially etched into to form alternating regions of elevational depressions and elevational protrusions in the uniform composition material. A plurality of magnetic tracks is formed over and which angle relative to the alternating regions. Interfaces of immediately adjacent of the regions individually form a domain wall pinning site in individual of the magnetic tracks. Other methods, including memory devices independent of method, are disclosed.
