Abstract
A data storage device including, in one implementation, a memory device and a controller configured to configured to retrieve a plurality of physical memory addresses from a first lookup table in the non-volatile memory. Each physical memory address is a combination of a word line and a string number of the non-volatile memory and the each physical memory address has a first number of bits. The controller is further configured to generate a plurality of encoded values by encoding the plurality of physical memory addresses. Each of the plurality of encoded values has a second number of bits that is smaller than the first number of bits. The controller is further configured to store the plurality of encoded values in the first lookup table, generate a logical to encoded value look-up table with the plurality of encoded values, and store the logical to encoded value look-up table in the memory.
