Abstract:
1. A magnetic random access memory comprising: memory cells which are stacked at stages, using a magnetoresistive effect; a read select transistor which commonly connects to one terminal of each of said memory cells; bit lines which are arranged in correspondence with said memory cells and extend in a first direction; a read word line which is connected to a source/drain of said read select transistor and extends in a second direction perpendicular to the first direction; and a decode line which is connected to a gate of said read select transistor and extends in the first direction, wherein each of said memory cells has the other terminal independently connected to one of said bit lines, said bit lines are electrically isolated from each other in a read mode, the data is independently written into the memory cells, and an imaginary line extending from a source of the read select transistor to a drain thereof is orthogonal to a read word line connected to the gate of the read select transistor.
