本篇文章主要介绍了"Nand Flash ECC algorighm"，主要涉及到Nand Flash ECC algorighm方面的内容，对于Nand Flash ECC algorighm感兴趣的同学可以参考一下。
ECC algorithm correction strength (number of bit errors that can be corrected) depends on the ECC algorithm used
to correct the errors (these algorithms may be implemented in either hardware or software).
codes can only correct single bit errors. Reed-Solomon code can correct more errors and is used on many of
the current controllers. BCH (Bose, Ray-Chaudhuri, Hocquenghem) codes can also correct multiple bit errors
and are becoming popular because of their improved efficiency over Reed-Solomon.
