Paragraph Number

198

The deviation module 404, in one embodiment, determines whether the read bias of the data set deviates from the known bias by comparing the read bias to the known bias. The deviation module 404 may compare the read bias to the known bias by counting the number of binary ones and the number of binary zeroes in the data set to determine the ratio of binary ones and binary zeroes in the data set and comparing that ratio to a ratio of the known bias. In a further embodiment, the deviation module 404 may search for and/or count the occurrences of an expected pattern or other expected attribute of the known bias and compare the results of a similar search and/or count in the data set to the expected attribute. In certain embodiments, the ECC decoder 322 indicates to the deviation module 404 that the read bias of the data set deviates from the known bias by providing an error bias for the data set to the configuration module 352, or the like.
