    • A method of storing and accessing an error correcting code in NAND Flash, includes utilizing n pages of a block of the NAND Flash as an extended space of a spare area, n≦1, wherein when writing data, the data is stored in a data area of a sector, and when the error correcting code needs a space which has correcting capability larger than 16 bytes, first 16 bytes of the error correcting code is stored in the 16 bytes spare area, and the remaining of the error correcting code is stored in the extended space of the spare area corresponding to the sector. Therefore, the method develops new storing space for the error correcting code, arranges the error correcting code in sequence of data blocks in sub-space, and loads the error correcting code into system memory for the decoder before reading original data.
    • 一种在NAND闪存中存储和访问纠错码的方法,包括利用NAND Flash的块的n页作为备用区的扩展空间,其中当写数据时,数据被存储在数据中 区域,并且当纠错码需要具有大于16字节的校正能力的空间时,纠错码的前16个字节被存储在16字节备用区中,并且剩余的纠错码被存储 在对应于扇区的备用区域的扩展空间中。 因此,该方法开发了用于纠错码的新的存储空间,在子空间中排列数据块的纠错码,并在读取原始数据之前将纠错码加载到解码器的系统存储器中。
