Abstract
A non-volatile memory device includes a volatile memory, a non-volatile memory, and a controller. The controller is configured to map logical addresses for stored data to physical addresses of the stored data in the non-volatile memory using a logical-to-physical mapping structure stored partially in the volatile memory and at least partially in the non-volatile memory. The controller is configured to perform a storage capacity recovery operation for a region of the non-volatile memory that is selected based at least partially on a number of mappings for the region likely to be stored in the volatile memory for the storage capacity recovery operation.
