Paragraph Number

126

In one embodiment, the secondary ECC module 304 may use a hard-decision decoder that uses no soft information, in connection with the soft-decision decoder used by the soft decision module 402. In some embodiments, the soft-decision decoder may be able to correct more errors in an ECC chunk than the hard-decision decoder, but the soft-decision decoder may use more time and/or computational resources than the hard-decision decoder. In further embodiments, the secondary ECC module 304 may use the hard-decision decoder to attempt to decode the at least one ECC chunk, and may activate the soft decision module 402 in response to determining that the at least one ECC chunk is uncorrectable using the hard-decision decoder with the secondary/inner error correcting code.
