Abstract: A data storage device using a FLASH memory with replay-protected blocks. The storage space of the FLASH memory is divided into blocks and each block is further divided into pages. A controller is provided in the data storage device to couple to the FLASH memory. The controller manages at least one replay-protected memory block of the FLASH memory. The controller programs two pages into the at least one replay-protected memory block and each page is programmed with a write count of the at least one replay-protected memory block.

Abstract: A memory device is provided. A processor accesses non-volatile memories via channels and generates a status table according to at least one command of a command queue. The status table records a plurality of tasks. Each task corresponds to one read status and one channel number. The processor selects a plurality of specific tasks from the tasks to serve as a first task set and simultaneously performs all the selected specific tasks with different channel numbers. When the read status of a first specific task matches a first predetermined status, the processor retrieves a logical-to-physical address mapping table relating to the logical address of the first specific task. When the read status of the first specific task matches a second predetermined status, the processor retrieves data relating to the logical address of the first specific task.

Abstract: The present invention provides a data storage device including a flash memory, a random access memory, and a controller. The controller selects a first read command where the required mapping table has already been loaded on the random access memory from a plurality of read commands. Before a first read task prepared by the first read command is executed, the controller selects a second read command from the remaining read commands, selectively reads a first data sector of the first read command and the mapping table of the second read command at the same time, or reads the first data sector and a second data sector of the second read command at the same time.

Abstract: A data storage device using a FLASH memory with replay-protected blocks. The storage space of the FLASH memory is divided into blocks and each block is further divided into pages. A controller is provided in the data storage device to couple to the FLASH memory. The controller manages at least one replay-protected memory block of the FLASH memory. The controller programs a success flag and a write count into a system block of the FLASH memory after the controller programs two pages into the at least one replay-protected memory block of the FLASH memory. The controller may perform a power restoration process based on the success flag of the system block or/and based on the amount of programmed pages of the at least one replay-protected memory block.
