摘要:
A magnetic random access memory includes at least a first-direction write current line and multiple second-direction write current line, intersecting with the first-direction write current line in substantial perpendicular and forming several intersecting regions. Multiple magnetic memory cells are respectively located at the intersecting regions for receiving an induced magnetic field in a time sequence. Every at least two adjacent memory cells are in parallel or series connection, to form at least one memory unit. An easy axis of a free layer of each magnetic memory cell is substantially perpendicular to a magnetization of a pinned layer. The easy axis and the first-direction write current line form an including angle of about 45°. A read bit-line circuit connects to a first terminal of the memory unit. A read word-line circuit connects to a second terminal of the memory unit.
