Abstract:
1. A memory cell comprising: (a) a magnetic element having a first segment, a second segment and a third segment for storing first, second and third remnant magnetic fields in response to a write signal, wherein each of the first, second and third remnant magnetic fields has a first direction or a second direction, and wherein when said first, second and third remnant magnetic fields are in said first direction the memory cell is in a first orientation, and wherein when said first, second and third remnant magnetic fields are in said second direction the memory cell is in a second orientation; (b) a write line for applying said write signal to said magnetic element, a portion of the write line having a shape that corresponds to the first, second, and third segments of the magnetic element to completely cover the magnetic element; and (c) a sensor for detecting the orientation of the memory cell.
