Abstract
Embodiments of the present disclosure relate to a memory system and an operating method thereof. According to the embodiments of the present disclosure, the memory system may completely scan each of one or more target memory blocks among the plurality of memory blocks, once in each scan period to detect an error in data stored in the corresponding target memory block and may block an attempted second scan of each target memory block in a scan period in which the corresponding target memory block has already been scanned until the scan period is completed.
Claims15
A memory system comprising:
- a memory device including a plurality of memory blocks;
- and
- a memory controller in communication with the memory device to control the memory device,
- wherein the memory controller is configured to:
- completely scan each of one or more target memory blocks, among the plurality of memory blocks, once in each scan period to detect an error in data stored in the corresponding target memory block;
- and
- block an attempted second scan of each target memory block in a scan period in which the corresponding target memory block has already been scanned until the scan period is completed.
An operating method of a memory system including a memory device with a plurality of memory blocks, the operating method comprising:
- selecting one or more target memory blocks among the plurality of memory blocks at each of plural scan periods;
- and
- executing, during a first scan period of the plural scan periods, a scan operation for detecting an error in data stored in each target memory block once;
- wherein the scan operation for each target memory block is controlled such that a subsequent scan operation is not performed on any of the target memory blocks on which a scan operation has been previously executed during the first scan period until the first scan period is completed.
