Abstract:
1. A magnetic memory device comprising: a rectangular memory cell array including a plurality of MTJ elements provided at the coordinates (x, y) (x being an integer at least 0 and at most m [m is a natural number], and y being an integer at least 0 and at most n [n being a natural number]) of a first plane defined by an x-axis and a y-axis crossing at right angles; a plurality of first write lines passing the MTJ elements and extending in a direction neither perpendicular nor parallel to a magnetization easy axis direction of the MTJ elements, one end of at least one of the first write lines passing an upper periphery or a lower periphery of the memory cell array, and another end of the at least one of the first write lines passing a left periphery or a right periphery of the memory cell array; a plurality of second write lines, the first write lines and the second write lines sandwiching the MTJ elements; a plurality of first write line drivers connected to both ends of the first write lines, one of a pair of the first write line drivers connected to both ends of at least one of the first write lines being located outside the upper periphery or the lower periphery and another one of the pair of the first write line drivers being located outside the left periphery or the right periphery; and a plurality of second write line drivers connected to both ends of the second write lines.
