Negative Bias Temperature Instability (NBTI) and Positive Bias Temperature Instability (PBTI) are the two important reliability issues that degrade the SRAM cell stability over time. In this paper, we analyze the impact of NBTI and PBTI on 8T SRAM cells, and propose a stability improvement technique...
