Trap generation is hard to estimate in a flash cell due to a dynamic stress field during program and erase (P/E). With the knowledge of the time-dependence of erase stress field based on Fowler-Nordheim (FN) tunneling, the V T roll up during dynamic stress is evaluated by incorporating field-dependent oxide trap generation. The extracted VT degradation slope during constant FN stress can be applied quantitatively to predict the VT during dynamic stress.
