Abstract: A read leveling method for a memory device is provided. The memory device includes a first memory block and at least a second memory block. The read leveling method includes the following steps. Determining whether a block read count of the first memory block is larger than or equal to a first threshold. Detecting a page read count of a page of the first memory block when the block read count of the first memory block is larger than or equal to the first threshold. Determine whether the block read count of the first memory block is larger than or equal to a second threshold. Move data of one of the page of the first memory block to a page of the second memory block when the block read count of the first memory block is larger than or equal to the second threshold.

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.

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.
