摘要
Program charge effect on random telegraph noise (RTN) behavior in multi-level floating gate (FG) memory is investigated. RTN can be observed in inversion region and accumulation region for low and high threshold voltage (V-th) states, respectively. As V-th increases, capture time tau(c) decreases and emission time tau(e) increases. The RTN is induced by deeper and higher energy level traps as V-th increases. A physical model is proposed to interpret the phenomena based on change of "trap detection window".
