At the same time,the embedded OTP product(64 k8 bit)data retention capability is better than 10 years.
5μm叠柵一次编程(OTP)存储器工艺进行研究,通过选择介质(ONO)工艺条件,选择合适单元尺寸,增加(SIN)保护,优化单元侧面工艺等,使得存储单元在250℃高温24h加速老化后写入阈电压漂移小于10%,嵌入式OTP产品(64k*8位)可靠性评估存储器的数据保持能力大于十年。
By comparison on the effects of quantum confinement and Coulomb blockade on Fermi level of metal nanocrystal,it is found that Coulomb blockade could seriously deteriorate the data retention capability of metal nanocrystal memory(MNCM)device.
对比分析讨论了量子限制效应与库仑阻塞效应对金属纳米晶费密能级的影响后,发现库仑阻塞效应会严重削弱器件数据保持能力。
