Content

The configuration module 352, in one embodiment, uses a known bias and/or an error bias for a data set from the ECC decoder 322 in response to one or more correctable bit errors in the data set. In a further embodiment, the configuration module 352 uses an expected bias that is based on a reversible biasing algorithm as a known bias. In certain embodiments, the expected bias is used as the known bias in response to one or more uncorrectable bit errors in the data set. An error bias from the ECC decoder 322 may not be available to the configuration module 352 for uncorrectable bit errors because the uncorrectable bit error condition makes the bias undefined. For uncorrectable bit errors in a data set, in certain embodiments, the read bias of the data set may deviate from the known, expected bias for the data set more than for correctable bit errors, because of the greater severity of the errors. Due to the greater magnitude of deviation of the read bias of a data set from the known, expected bias of the data set for uncorrectable bit errors, the bias information from the inverse bias module 332 may provide a better indicator of a direction for a configuration parameter adjustment 358 for uncorrectable bit errors than for correctable bit errors.
