Defect and Fault Modeling Framework for STT-MRAM Testing
نویسندگان
چکیده
STT-MRAM mass production is around the corner as major foundries worldwide invest heavily on its commercialization. To ensure high-quality products, effective yet cost-efficient test solutions are of great importance. This article presents a systematic device-aware defect and fault modeling framework for to derive accurate models which reflect physical defects appropriately, thereafter optimal solutions. An overview classification manufacturing in STT-MRAMs provided with an emphasis those related fabrication magnetic tunnel junction (MTJ) devices, i.e., data-storing elements. Defects MTJ devices need be modeled by adjusting affected technology parameters subsequent electrical fully capture impact both device's properties, whereas interconnects can linear resistors. In addition, complete single-cell space nomenclature defined, analysis methodology proposed. demonstrate use proposed framework, resistive interconnect pinhole analyzed single 1T-1MTJ memory cell. Test detecting these also discussed.
