    Abstract: The memory system has an overwrite operation and an operation control method thereof. A nonvolatile memory device has a plurality of memory blocks including a plurality of memory cells stacked in a direction perpendicular to a substrate. When data of memory cells connected to a word line of a selected memory block is read, the need of reclaim is determined based on an error bit level of the read data. In the case that memory cells having an erase state among the memory cells connected to the word line become a soft program state, the read data is overwritten in the memory cells connected to the word line of the selected memory block.

    Abstract: A method of operating a data storage device includes programming non-fully programmed memory blocks at a point in time when a reference time elapses from a point in time when each of the memory blocks is physically erased, acquiring a first interval and a second interval, calculating a disturb index based on the first interval and the second interval, selecting a victim block for garbage collection based on the disturb index, and copying valid page data of the victim block into a free block. The first interval is defined by a point in time when each of the memory blocks is physically erased and a point in time when each of the memory blocks is fully programmed. The second interval is an interval during which a fully programmed state is maintained after a point in time when each of the memory blocks is fully programmed.

    Abstract: A storage device includes a nonvolatile memory device and a controller. The nonvolatile memory device includes multiple memory blocks, each of which includes memory cells. The controller reads data from selected memory cells of a memory block selected from the memory blocks during a read operation. The selected memory cells correspond to both a word line and a string selection line selected as a read target. The controller increases a read count by a read weight corresponding to the selected word line and string selection line of the selected memory block, and performs a refresh operation on the selected memory cells if the read count reaches a threshold value. In the selected memory block, two or more read weights are assigned according to locations of the string selection lines and the word lines.

    Abstract: Random sequence data is sequentially generated based on a seed assigned to a selected memory space, and one of access-requested segments of the selected memory space is logically combined with the sequentially generated random sequence data to transfer the access-requested segment. The sequentially generating and the logically combining are iteratively performed until remaining access-requested segments all transferred.
