  journal={2014 IEEE International Reliability Physics Symposium},
Recent advances in understanding Bias Temperature Instability (BTI) in terms of individual gate oxide defects has created a paradigm shift towards describing degradation in terms of time-dependent variability. This added time dimension to the variability analysis has proven to be a considerable design challenge. Moreover, the non-normally distributed ΔVTH shifts create compatibility issues with the current SotA statistical assessments techniques for evaluating high sigma yield of SRAM cells… CONTINUE READING
