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.

Abstract: A method for writing data into a persistent storage device includes grouping a plurality of data entries stored in a temporary storage device to form a data unit, such that the data unit has a size equal to an integer multiple of a size of an access unit of the persistent storage device. The method further includes writing the data unit into the persistent storage device.
