    摘要: In one example, an MRAM memory array includes a plurality of word lines, a plurality of bit lines crossing the word lines, and a plurality of first and second diodes, and magnetic tunnel junction memories. Each first diode includes a cathode, and an anode coupled to each bit line. Each second diode includes an anode, and a cathode coupled to each word line. The magnetic tunnel junction memories include a pinned layer, a free layer, and a non-magnetic layer. The non-magnetic layer is located between the pinned layer and the free layer. Each diode is positioned at crossing points of the bit lines and the word lines and connected between the first diode at the corresponding crossing bit line and the second diode at the corresponding crossing word line.

    摘要: An MRAM cell including an MRAM cell stack located over a substrate and first and second write lines spanning at least one side of the MRAM cell stack and defining a projected region of intersection of the MRAM cell stack and the first and second write lines. The MRAM cell stack includes a pinned layer, a tunneling barrier layer, and a free layer, the tunneling barrier layer interposing the pinned layer and the free layer. The first write line extends in a first direction within the projected region of intersection. The second write line extends in a second direction within the projected region of intersection. The first and second directions are angularly offset by an angle ranging between 45 and 90 degrees, exclusively. At least one write line may be perpendicular to the easy axis of free layer, while the other line may be rotated off the easy axis of the free layer by an angle which is larger than zero, such as to compensate for a shifting astroid curve.
