Patent ID: 8009467

Claim:
A magnetic random access memory comprising: a memory cell array; a first word line and a second word line each connected in common to a group of memory cells arranged in a first direction in said memory cell array; a plurality of blocks arranged in a matrix form; a common word line connected in common to a group of blocks arranged in said first direction among said plurality of blocks; and a bit line pair connected in common to a group of blocks arranged in a second direction intersecting with said first direction among said plurality of blocks, wherein said bit line pair includes a first bit line and a second bit line, wherein each of said plurality of blocks comprises: a plurality of memory cells in said memory cell array, each of the plurality of memory cells having a first transistor and a magnetoresistance element; and a second transistor to which said plurality of memory cells are connected in parallel, wherein a gate of said second transistor is connected to said common word line, a gate of said first transistor is connected to said first word line, one of a source and a drain of said first transistor is connected to said first bit line, the other of the source and the drain of said first transistor is connected to one end of said magnetoresistance element and connected to said second bit line through said second transistor, and the other end of said magnetoresistance element is connected to said second word line.
