Patent ID: 7614027

Claim:
A method for forming a magnetic random access memory (MRAM) array, comprising: forming a first wiring layer of approximately parallel word conductors, a second wiring layer of approximately parallel bit conductors and a third wiring layer of approximately parallel select conductors such that the word, bit and select conductors in the first, second and third wiring layers cross at a number of intersections; at least one of the first, second and third wiring layers being formed so as to be non-orthogonal with respect to a remaining at least one of the first, second and third wiring layers; and forming a layer of magnetic storage elements, wherein the magnetic storage elements are proximately located to the intersections and are magnetically coupled to magnetic fields generated when current flows in word lines, when current flows in bit lines, and when current flows in select lines, wherein a desired magnetic storage element is written using three magnetic fields, wherein the three magnetic fields used to write the desired magnetic storage element include a first magnetic field produced by an energized word conductor in the first wiring layer, a second magnetic field produced by an energized bit conductor in the second wiring layer, and a third magnetic field produced by an energized select conductor in the third wiring layer.
