Patent ID: 8923042

Claim:
A magnetic random access memory, comprising: a magnetization fixed layer having a fixed magnetization; a magnetic recording layer through which a write current flows in an in-plane direction of said magnetic recording layer, said magnetic recording layer including a magnetization free region and first and second magnetization fixed regions; a non-magnetic layer provided between said magnetization free region and said magnetization fixed layer; first and second interconnections electrically connected to said first and second magnetization fixed regions, respectively, wherein said write current flows through said first and second interconnections; and a third interconnection electrically connected to said magnetization fixed layer, wherein a read current flows through said third interconnection, wherein said magnetization free region has a reversible magnetization, said first magnetization fixed region is coupled to said magnetization free region and has a fixed magnetization, and said second magnetization fixed region is coupled to said magnetization free region and has a fixed magnetization, at least one of said first to third interconnections including a first portion extending in a first direction, a second portion extending in the first direction, and a third portion connected between said first and second portions and opposed to said magnetic recording layer, wherein said first, third, and second portions are arrayed in the first direction, a width of said third portion in a second direction perpendicular to said first direction being larger than widths of said first and third portions in said second direction, and wherein said at least one of said first to third interconnections is said third interconnection, and said third portion is electrically connected to said magnetization fixed layer through a via contact.
