Abstract
A method for operating a data storage device including memory regions each including memory units of levels, the levels respectively corresponding to bitmaps, and each of the bitmaps including entries respectively corresponding to the memory regions includes controlling a read operation for a first memory unit of a first level among the levels in a first memory region among the memory regions; increasing a read count by checking a first entry corresponding to the first memory region in a first bit map corresponding to the first level, wherein each of entries included in the first bitmap reflects whether a corresponding memory region is included in at least one second memory region in which a memory unit of the first level has been read, during a predetermined period before the read operation for the first memory unit; and performing a management operation for the memory regions, based on the read count.
