US Patent 10275297 Generating soft read values which optimize dynamic range

A plurality of bins and a plurality of soft read values are stored in a lookup table where those bins that are either a leftmost bin or a rightmost bin correspond to soft read values having a maximum magnitude. Bin identification information is received for a cell in solid state storage. A soft read value is generated for the cell in solid state storage, including by: accessing the lookup table, mapping the received bin identification information to one of the plurality of bins in the lookup table, and selecting the soft read value in the lookup table that corresponds to the bin which is mapped to.
