Paragraph Number

291

Using each bit stored in multi-level storage cells to determine a read voltage threshold adjustment, in certain embodiments, can increase the accuracy of the read voltage threshold adjustment, but may increase the number of read operations or add complexity to the determination. In one embodiment, if the ECC decoder 322 detects a data error in an upper page of a grouping of multi-level storage cells, the data set read module 402 retrieves one or more lower pages for the grouping and the configuration module 352 adjusts a read voltage threshold for the grouping based on the lower pages.
