Abstract
Systems, circuits and methods for controlling write operations in Spin Transfer Torque Magnetoresistive Random Access Memory (STT-MRAM) are disclosed. A reduced bit cell size is achieved by arranging the source lines (SL) substantially in parallel with the word lines (WL) and substantially perpendicular to the bit lines (BL). Further, in one embodiment during a write operation, a high logic/voltage level is applied to the bit lines of unselected bit cells to prevent an invalid write operation.
