    Abstract: An exemplary embodiment provides an electronic device including a controller, a first flash memory and a second flash memory. The first flash memory stores a first data sector. The second flash memory stores a second data sector, wherein the first data sector and the second data sector are the same, and the first data is stored in a plurality of pages of the first flash memory and the second data is stored in a plurality of pages of the second flash memory. The controller produces a third data according to the first data sector and the second data sector when the controller determines that the first data sector stored in the first flash memory is damaged.

    Abstract: A flash device is provided. A flash memory includes a plurality of pages. A controller coupled to the flash memory includes an operating unit, an error correction code (ECC) decoder and a processing unit. The operating unit receives a plurality of bytes of the page which are from the flash memory and corresponding to a read command, and obtains an operating result according to a logic level of each bit of each of the bytes. The ECC decoder decodes the bytes of the page according to an ECC code. The processing unit determines whether the page is valid data according to the decoded bytes, and determines whether the page is an empty page according to the operating result when the page is not the valid data.

    Abstract: A data storage device and an operating method for a FLASH memory are disclosed. The disclosed data storage device includes a FLASH memory and a controller. The FLASH memory provides a storage space which is stored with a first storage type system information and a second storage type system information. Data recognition for the first storage type system information is stricter than that of the second storage type information. The controller reads the storage space of the FLASH memory and performs an error checking and correction process on data read from the storage space, and, based on the storage type system information, among the first and second storage type information, which first passes the error checking and correction process, the controller operates the FLASH memory.
