Abstract
An apparatus and method for managing a mapping table of a non-volatile memory are provided. The apparatus includes a non-volatile memory having memory cells, each of which stores data bits in a plurality of pages included in a block according to a plurality of states, each of which has at least two bits, an operating time measuring unit measuring a write operation time on each of the plurality of pages included in the block, and a mapping table generating unit dividing the pages into a plurality of groups according to the measured write operation time and generating a mapping table by using the divided groups.
