1. A magnetic memory device, comprising:
- a perpendicular-anisotropy magnetic reference layer (or layer structures) whose magnetization is fixed;
a perpendicular-anisotropy magnetic storage layer (or layer structure) whose magnetization can be changed is changeable;
a dielectric layer as tunneling barrier sandwiched between said perpendicular-anisotropy magnetic reference layer and said perpendicular-anisotropy magnetic storage layer;
a fixed in-plane anisotropy magnetic layer (or layer structure) where any current passing through gets spin polarized;
a non-magnetic layer sandwiched between said perpendicular-anisotropy magnetic storage layer and said fixed in-plan anisotropy magnetic layer.

Abstract
A new magnetic memory cell comprises a perpendicular-anisotropy tunneling magnetic junction (TMJ) and a fixed in-plane spin-polarizing layer, which is separated from the perpendicular-anisotropy data storage layer of tunneling magnetic junction by a non-magnetic layer. The non-magnetic layer can be made of metallic or dielectric materials.
