Patent ID: 7616477

Claim:
A memory cell comprising: (a) a plurality of magnetic elements; (b) a sensor having a sensing region; and (c) a single write line for storing a remnant magnetic field in each of the plurality of magnetic elements, wherein, when the memory cell is in a first orientation, the magnetic field in each of the plurality of magnetic elements has a first direction with respect to the sensing region and when the memory cell is in a second orientation, the magnetic field in each of the plurality of magnetic elements has a second direction with respect to the sensing region, wherein the memory cell has first, second and third magnetic elements, and wherein the write line has; (i) a first segment aligned with the first element; (ii) a second segment aligned with the second element; and (iii) a third segment aligned with the third element, wherein the second magnetic element has a trapezoidal cross-section and wherein the first and second magnetic elements positioned adjacent to the second magnetic element are shaped to correspond to the shape of the second magnetic element.
