Content
For certain types of multi-level storage cells, the middle read voltage threshold 662b and the adjacent L1 and L2 states may be more sensitive to read disturb or other factors that can cause read voltages to drift. Further, as described above, in certain embodiments, the LSB and the MSB of a single multi-level storage cell may represent data stored in different physical pages. Using a single bit from each of a plurality of multi-level storage cell as a data set, in one embodiment, may reduce a number of read operations to retrieve the data set. In other embodiments, use of a single bit from each of a plurality of multi-level storage cells in the lower page simplifies a process of detecting deviation and direction of a read bias from a known bias for multi-level storage cells.
