Patent ID: 7939869

Claim:
A semiconductor device comprising: a semiconductor substrate; a first source region and a first drain region formed at a distance from each other in the semiconductor substrate; a first channel region provided between the first source region and the first drain region; a first gate insulating film formed on the first channel region; a first gate electrode formed on the first gate insulating film; a first source electrode formed above the first source region and including a ferromagnetic layer having an easy axis of magnetization in a first direction; a first drain electrode formed above the first drain region and including a ferromagnetic layer magnetized in a second direction at an angle larger than 0 degrees but not larger than 180 degrees with respect to the first direction; and a second drain electrode formed above the first drain region, being located at a distance from the first drain electrode, and including a ferromagnetic layer magnetized in a direction substantially antiparallel to the second direction.
