A Spin Transfer Torque Magnetoresistive Random Access Memory (STT-MRAM) bit cell is provided. The STT-MRAM includes a rectangular bottom electrode (BE) plate, and a storage element on the rectangular bottom electrode (BE) plate. A difference between a width of the rectangular bottom electrode (BE) plate and a width of the storage element is equal to or greater than a predetermined minimum spacing requirement. A width of the bottom electrode (BE) plate is substantially equal to a width of an active layer or a width of a plurality of metal layers. |
