摘要： A storage device includes a nonvolatile memory device and a controller. The nonvolatile memory device includes a plurality of memory blocks, each of which includes string selection transistors connected to a plurality of string selection lines, ground selection transistors connected to a plurality of ground selection lines, and memory cells connected to a plurality of word lines. The controller reads valid data groups of a first memory block and writes the read valid data groups in a second memory block, during a read reclaim operation. The controller assigns locations of the second memory block, at which the valid data groups are written, based on read counts of the valid data groups.

摘要： A method of operating a memory system includes; storing data in a buffer region of the nonvolatile memory, later issuing a migration request directed to the data stored in the buffer region and executing a migration operation to move the data from buffer region to a main region of the nonvolatile memory device. Upon completion of the migration operation, marking a migration operation completion time, and after an initial verify shift (IVS) time has elapsed following the migration operation completion time, updating a mapping table associated with the data in view of the executed migration operation.
