A memory system includes a memory controller, a memory cell array, a location information storage unit, an address mapping table, an address conversion unit, and a mapping information calculation unit. The memory controller generates a logical address signal and an address re-mapping command. The memory cell array includes a plurality of logic blocks. The location information storage unit stores location information corresponding to faulty memory cells included in the memory cell array. The address mapping table stores address mapping information. The address conversion unit converts the logical address signal to a physical address signal corresponding to the memory cell array based on the address mapping information. The mapping information calculation unit generates the address mapping information to reduce the number of logic blocks including the faulty memory cells based on the location information upon the mapping information calculation unit receiving the address re-mapping command.
