Effect of trapped charge accumulation on the retention of charge trapping memory

【摘要】 <正>The accumulation process of trapped charges in a TANOS cell during P/E cycling is investigated via numerical simulation. The recombination process between trapped charges is an important issue on the retention of charge trapping memory. Our results show that accumulated trapped holes during P/E cycling can have an influence on retention,and the recombination mechanism between trapped charges should be taken into account when evaluating the retention capability of TANOS.更多还原
