如果在掉电过程中发现了program状态出错,这时的信息还在我们的buffer里,有两种可供选择的方法,第一是重新再次program,第二是等上电时像read error一样用RAID来纠错。选择哪种方法要根据NAND出错的概率来计算,如果program fail和UECC发生在同一个RAID set上的概率低于产品设计时的UECC允许概率,则可以将其当做read er...

1、对于初始坏块,坏块跳过会通过BBT将对应的坏块跳过,直接将数据存入下一个好块。 2、对于新增的坏块,将此坏块更新到BBT中,将坏块中的有效数据转存到下一个好块中,以后每次再做相应的Read、Program或者Erse时直接跳过此坏块。 坏块替换策略(某Nand Flash厂商建议的做法) 坏块替换,是指使用预留区中的好块来替换使...
