Paragraph Number

153

In one embodiment, the data set or packet that the configuration module 352 receives has a known bias. The data set or packet has a known bias for one of at least three reasons. First, the data set or packet may have a known bias because the bias module 318 biased the data set or packet when the data set or packet was written. In one embodiment, the bias module 318 and/or the inverse bias module 332 cooperate with the configuration module 352, communicating the known bias to the configuration module 352. Second, the data set or packet may have a known bias because the data set or packet is read from a virgin, unwritten region of the solid-state storage media 110. For example, in one embodiment, virgin, unwritten regions of the solid-state storage media 110 may typically have a known bias of exclusively binary ones or exclusively binary zeroes in an unwritten state. Third, the data set or packet may have a known bias because the ECC decoder 322 has corrected the data set or packet and has determined the original, correct values of one or more bits of the data set that were in error. The correct values for the bits in the data set comprise this known bias. A deviation from the known bias caused by errors in the data set is an error bias.
