Abstract: A data backup method for a flash memory module is provided. The flash memory module includes a plurality of flash memory units. In the data backup method, a controller is first provided to receive a backup function enabling signal. The controller then configures the flash memory units according to the backup function enabling signal such that at least one of the flash memory units is configured as a backup storage area and the flash memory units that are not in the backup storage area are configured as a main storage area. The controller then checks and receives an updated status of important data in the main storage area and backs up the important data into the backup storage area according to the updated status. Accessing to the backup storage area and accessing to the main storage area by the controller are independent.

Abstract: An embodiment of the invention provides a data storage device and data management method thereof. The data storage device is coupled to a host, and includes a storage media having data sectors for storing data and a controller. The controller is coupled to the storage media for sequentially receiving one or more read commands and corresponding one or more logical addresses thereto, reads a plurality of first data sectors from the storage media according to the read commands and the corresponding logical addresses, outputs data of the first data sectors to the host, calculates a valid duration required for the one or more read commands, calculates an average data throughput according to the number of the first data sectors and the valid duration, and determines whether the average data throughput exceeds a predetermined threshold. When the average data throughput exceeds the predetermined threshold, the controller performs a blocking procedure to prevent the storage media from being accessed.

Abstract: In order to correct errors of a first page on one plane in a two-plane NAND flash memory, use data of a second page on another plane to mix the encoding and leverage the error correction code of the first page. Each of the error correction codes of the first page and the second page is divided into an inner correction code and a cross correction code. The inner correction codes are used to correct errors of their own pages and the cross correction codes are used to correct errors of two distinct groups, grouped from the even and odd bytes of the two pages respectively. The second page, with fewer errors, is therefore used to enhance the correcting ability of the first page, without lengthening the error correction code of the first page.

Abstract: A storage device includes a control unit, a first voltage supply unit for supplying a first working voltage to the control unit, N memory units, a second voltage supply unit for supplying a second working voltage to each memory unit, a logic gate, a first voltage detecting unit and a second voltage detecting unit. Once the first voltage detecting unit detects that the first working voltage of the control unit is abnormal, the logic gate outputs a first write protect signal to notify the control unit and control the memory units to enter a write protect mode. Once the second voltage detecting unit detects that the second working voltage of one or more memory units is abnormal, the logic gate outputs a second write protect signal to notify the control unit and control the one or more memory units to enter the write protect mode.

Abstract: An operation method of an anti-virus storage device having a storage disk and a read-only memory includes connecting the storage device to a host and displaying a single disk name on an interface of an operating system of the host, executing an anti-virus application program corresponding to the operating system, wherein the anti-virus application program is stored in the read-only memory, generating a hidden partition in the storage disk, wherein the hidden partition comprises an anti-virus engine and a virus pattern, and starting up the anti-virus engine, enabling a main storage partition and only displaying a disk name of the main storage partition on the interface of the operating system. If the anti-virus application program has no an execution file corresponding to the operating system, a user using the anti-virus storage device decides whether enables and displays the main storage partition without executing the anti-virus application program.
