Paragraph Number

In one embodiment, the deviation module 404 determines that a read bias for a data set deviates from a known bias with which the data set was originally stored. The read bias of the data set deviates from the known bias when there is a difference between the read bias and the known bias. In one embodiment, where the known bias is exact, such as where the known bias includes error corrected bit values or where the bias module 318 biases to an exact bias, the deviation module 404 may determine that any difference between a read bias and the known bias comprises a deviation from the known bias. In other embodiments, the known bias may include an average bias, an estimated bias, a distribution of biases, a range of biases, or the like. The deviation module 404, in these embodiments, may determine that a read bias outside of a range or distribution of known biases, at least a predefined deviation threshold away from a known bias, or the like deviates from the known bias.
