Patent ID: 8406046

Claim:
An initializing method of a magnetic random access memory which comprises: a magnetic record layer which is ferromagnetic; a ferromagnetic magnetization fixed layer whose magnetization is fixed; and a non-magnetic spacer layer provided between said magnetic record layer and said magnetization fixed layer, wherein said magnetic record layer comprises: a magnetization invertible region whose magnetization is invertible and which is connected to said magnetization fixed layer through said spacer layer; a first magnetization region which has a magnetization in a first direction and which is provided in parallel to said magnetization invertible region; a second magnetization region which has a magnetization in a second direction and which is provided in parallel to said magnetization invertible region; a first inclined region connected to said magnetization invertible region and said first magnetization region at a predetermined inclination angle; and a second inclined region connected to said magnetization invertible region and said second magnetization region at said inclination angle, said initializing method comprising: setting magnetization directions of said magnetization invertible region, said first magnetization region, said second magnetization region, said first inclined region, and said second inclined region to a same direction; applying a first magnetic field on a surface of said first inclined region at a first angle to invert the magnetization direction of said first inclined region; and applying a second magnetic field in a direction parallel to a surface of said second inclined region to invert the magnetization directions of said first magnetization region and said magnetization invertible region.
