Abstract
A memory device includes a memory controller and a non-volatile memory communicatively coupled to the memory controller and storing a mapping table and a journal table. The memory controller is configured to write data and a logical address of the data into the non-volatile memory, load mapping information related to the logical address of the data from the mapping table of the non-volatile memory into a mapping cache of the memory controller, update the mapping cache with an updated mapping relationship between the logical address of the data and a physical address of the data, and perform a journaling operation to write the updated mapping relationship into the journal table.
