Abstract

A method or apparatus that can form and test a data block variant by flipping a selected potentially bad bit that is consecutive with 1 or 2 sequences of several potentially good bits of a received block. The variant correctability test is optionally repeated several times before receiving another data block, in the event of ECC failures, each repetition using a different block variant.
