Abstract
A system and method for correcting errors in an ECC block using erasure-identification data when generating an error-locator polynomial. In an embodiment, a ECC decoding method, uses 'erasure' data indicative of bits of data that are unable to be deciphered by a decoder. Such a method may use an Berlekamp-Massey algorithm that receives two polynomials as inputs; a first polynomial indicative of erasure location in the stream of bits and a syndrome polynomial indicative of all bits as initially determined. The Berlekamp-Massey algorithm may use the erasure identification information to more easily decipher the overall codeword when faced with a error-filled codeword.
