Magnetic random access memory

摘要

The unit has a magnetic portion (82) provided in a recess (64) of an insulating layer (62). A non magnetic oxide portion (92) and a ferromagnetic portion (94) are provided in a recess of an insulation layer (84) covering the layer (62). The recess of the layer (84) exposes the portion (82) and a part of the layer (62) surrounding the portion (82). A corner area (95) is formed at the level of the periphery of the portion (92). An independent claim is also included for a method for manufacturing a magnetic memory unit.
