1. A method, comprising:
determining a plurality of interference states with respect to an interference source of a target row of a non-volatile memory to be read;
determining compensation shifts for the plurality of interference states by determining a compensation shift for each of two or more interference states of the plurality of interference states, wherein at least one of the compensation shifts is determined by extrapolating from another one of the compensation shifts; and
applying the compensation shifts for the plurality of interference states to reading the target row.
