Abstract

Spin Transfer Torque Magnetoresistive Random Access Memory (STT-MRAM) bit cells are disclosed. The bit cells include a source line formed in a first plane and a bit line formed in a second plane. The bit line has a longitudinal axis that is parallel to a longitudinal axis of the source line, and the source line overlaps at least a portion of the bit line.
