A file system including a first memory unit which is non-volatile and has a plurality of blocks, a control unit configured to select one of the plurality of blocks of the first memory unit, determine whether the selected block is a valid block, control a data write with respect to the selected block if the selected block is a valid block, divide the plurality of blocks into valid blocks and bad blocks by checking the plurality of blocks of the first memory unit, generate an address table by mapping the valid blocks and the bad blocks to addresses and control a loading of the address table generated, and a second memory unit which is volatile and stores the address table for the plurality of blocks of the first memory unit. An address table of a flash memory, which is a non-volatile memory, is stored in another memory |
