  • Abstract
    The effect of random telegraph noise (RTN) on write stability of SRAM cells in sub-0.4V operation is intensively measured and statistically analyzed. RTN of N-curves in Silicon-on-Thin-BOX (SOTB) cells is monitored. By developing statistical models, it is found that, different from bulk SRAM cells operating at high supply voltage (VDD), fail bit rate (FBR) at sub-0.4V is degraded by RTN. The origin of high FBR due to RTN at sub-0.4V is discussed.
