Claim:
1. A device for selecting a level for at least one read voltage for reading data stored in a multi-level memory device: wherein the multi-level memory device includes a plurality of memory blocks; wherein each of the plurality of memory blocks includes a plurality of word lines; and wherein each of the word lines is allocated to a plurality of memory pages and is indexed by a word line index, the device comprising: a first mapping unit for mapping each of the word line indices to one bin label, wherein the number of bin labels is smaller than the number of word lines; and a second mapping unit for mapping each of the bin labels to a voltage information being indicative for at least one read voltage, wherein the level for the at least one read voltage for reading data is selectable for each word line based on the respective word line index.
