    Abstract: The invention relates to a method, a non-transitory computer-readable storage medium and an apparatus for reading data with an optimization read voltage (RV) table. The method includes: determining one set of RVs for a designated memory-cell type according to a current environmental parameter of a NAND-flash module and content of the optimization RV table; and reading data on a page corresponding to the designated memory-cell type from the NAND-flash module with the set of RVs. The optimization RV table includes multiple records and each record includes one set of RV parameters and an environmental parameter associated with the set of RV parameters.

    Abstract: The invention relates to a method, a non-transitory computer-readable storage medium and an apparatus for dynamically updating an optimization read voltage (RV) table. The method includes: obtaining a data-read transaction and replying with the data-read transaction to a host side after listening to a first request for read-performance data, which is issued by the host side, thereby enabling the data-performance transaction to be used in an update of the optimization RV table for a designated memory-cell type; and programming multiple records of an updated optimization RV table for the designated memory-cell type into a designated location of the NAND-flash module after listening to a second request for updating the optimization RV table for the designated memory-cell type, which is issued by the host side. The data-read transaction includes a current environmental parameter of a NAND-flash module, the designated memory-cell type and a bit error rate (BER). Each record includes one set of RV parameters and an environmental parameter associated with the set of RV parameters.

    Abstract: The present invention provides a data storage device including a flash memory and a controller. The flash memory is capable of operating in a SLC mode and a non-SLC mode. The controller is configured to perform a first read operation to read a page corresponding to a first word line of the flash memory in the SLC mode according to a read command of a host, and perform an adjustable read operation when data read by the first read operation cannot be recovered by coding, wherein the controller is further configured to enable the flash memory to operate in the non-SLC mode in the adjustable read operation, and write logic 1 into a most-significant-bit page corresponding to the first word line in the non-SLC mode to adjust voltage distribution of the first page.
