PURPOSE: A flash memory management method for reducing merge operations in a flash translation layer using full associative sector translation technique and a device thereof are provided to delay merge operation of frequent rewriting. CONSTITUTION: A multi flash memory(130) includes multiple flash memories(132,134,136) divided into a data block area, a log block area, and a free block area. If available free space is not in the log block area and log block optimization is required, a flash translation layer(100) calculates log block invalidation operation time and merge operation time. If the log block invalidation operation time is smaller than the merge operation time, the flash translation layer performs log block invalidation.
