MBIST-supported Trim Adjustment to Compensate Thermal Behavior of MRAM


Abstract: "Spin Transfer Torque Magnetic Random Access Memory (STT-MRAM) is one of the most promising candidates to replace conventional embedded memory such as Static RAM and Dynamic RAM. However, due to the small on/off ratio of MRAM cells, process variations may reduce the operating margin of a chip. Reference trimming was suggested as one of the ways to reduce variation impact to the chi... » read more
