Patent ID: 8526222

Claim:
A magnetic random access memory comprising: a magnetic recording layer including a magnetization free region having a reversible magnetization, through which layer a write current is flown in an in-plane direction, said magnetic recording layer comprising, a first magnetization fixed region coupled with a first boundary of said magnetization free region and having a fixed magnetization, and a second magnetization fixed region coupled with a second boundary of said magnetization free region and having a fixed magnetization; a magnetization fixed layer having a fixed magnetization; a non-magnetic layer provided between said magnetization free region and said magnetization fixed layer; and a heat sink structure provided to be opposed to said magnetic recording layer and having a function of receiving and radiating heat generated in said magnetic recording layer; a first interconnection electrically connected with said first magnetization fixed region; and a second interconnection electrically connected with said second magnetization fixed region, wherein said write current is flown from said first magnetization fixed region to said second magnetization fixed region or from said second magnetization fixed region to said first magnetization fixed region, and wherein said heat sink structure is positioned between said first and second interconnections within the same interconnection layer as said first and second interconnections.
