Abstract
An operating method of a storage device includes reading a wear-out pattern of a memory block when a controller determines the memory block is a re-use memory block of a non-volatile memory device; selecting an operation mode corresponding to the read wear-out pattern using the controller; and transmitting the selected operation mode to the non-volatile memory device using the controller.
Claims10
An operating method of a storage device, the method comprising:
- reading a wear-out pattern of a memory block when a controller determines the memory block is a re-use memory block of a non-volatile memory device;
- selecting an operation mode corresponding to the wear-out pattern using the controller;
- and
- transmitting the operation mode to the non-volatile memory device using the controller.

- selecting an operation mode corresponding to the wear-out pattern using the controller;
- and
- transmitting the operation mode to the non-volatile memory device using the controller;
- performing a patrol read operation for the memory block before the memory block is reused;
- and
- determining whether a reclaim is necessary as a result of the patrol read operation.
