Abstract:
1. A magnetic memory cell comprising: a magnetic recording layer that is a ferromagnetic layer; and a pinned layer connected to said magnetic recording layer through a non-magnetic layer, wherein said magnetic recording layer includes: a magnetization switching region having reversible magnetization and facing said pinned layer; a first magnetization fixed region connected to a first boundary of said magnetization switching region and whose magnetization direction is fixed to a first direction; and a second magnetization fixed region connected to a second boundary of said magnetization switching region and whose magnetization direction is fixed to a second direction, wherein said first magnetization fixed region and said second magnetization fixed region are formed parallel to each other, wherein said first direction and said second direction are the same direction, wherein magnetization direction of said magnetization switching region is toward any of said first boundary and said second boundary, and a domain wall is formed at any of said first boundary and said second boundary in said magnetic recording layer.
