Abstract:
1. A magnetic random access memory, comprising: at lease a first-direction write current line; a plurality of second-direction write current lines, substantially perpendicularly intersecting with the first-direction write current line, forming a plurality of intersection regions; a plurality of magnetic memory cells, respectively located at the intersection regions, receiving an induced magnetic field in a time sequence, wherein the adjacent at least every two magnetic memory cells are connected in series or parallel, to form at least a memory unit, wherein an easy axis of a free layer of each of the magnetic memory cells is substantially perpendicular to a magnetization of a pinned layer, and an including angle of about 45 degrees is between the easy axis and the first-direction write current line; a read bit line circuit, connected to a first terminal of the memory unit; and a read word line circuit, connected to a second terminal of the memory unit.
