Magnetic random access memory

A magnetic random access memory comprising:

• a magnetic recording layer including a magnetization free region having a reversible magnetization, a first magnetization fixed region connected to a first boundary of said magnetization free region, and a second magnetization fixed region connected to a second boundary of said magnetization free region, through which layer a write current is flown in an in-plane direction;
• 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 first interconnection electrically connected to said first 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,
• wherein said first interconnection includes:
• an interconnection main body extending in a first direction in which said write current is flown;
• and
• a protrusion protruding from said interconnection main body in a second direction vertical to said first direction, said protrusion being opposed to said magnetic recording layer.
