A data storage device may include a storage including a plurality of storage regions each composed of a plurality of pages; and a controller. The controller is configured to select a plurality of target open regions from open regions among the storage regions on the basis of health information of the open regions, in each of which a programmed page and an unprogrammed page coexist, and perform control so that refresh operations for the respective target open regions are performed in a time-distributed manner.

Data storage device for refreshing data and operating method thereof

A memory system and a method of operating the memory system are provided. The memory system may determine, on a determination that the memory system enters thermal throttling mode, a target status read check period based on threshold voltage distribution offset for the target memory die, and set a timer to transmit a status read command for the target memory die to the memory device based on the target status read check period.
