Abstract: A non-volatile memory operated through multiple channels. The non-volatile memory includes a plurality of chip-enable-signal controlled areas, each containing a plurality of dies. Simultaneous operations on the different dies of at least one target chip-enable-signal controlled space corresponding to a target channel are allowed. The control unit scans the non-volatile memory to check the health status of the dies of the target chip-enable-signal controlled space to assign a plurality of logical enable signals of the target channel to correspond to the dies of the target chip-enable-signal controlled space.

Abstract: A storage device and a data storing method thereof are provided. The storage device includes a data storage medium and the control unit. The data storage medium includes a data storage area with a plurality of first type of data blocks. When a data reading operation is executed on a current data block of the data storage medium, the control unit determines whether a read count of the current data block is greater than a first threshold, determines whether the current data block is one of the first type of data blocks and generate a determination result according to the result, the control unit selects a plurality of first type of data blocks and switches the selected data blocks to a fast mode. Finally, the control unit moves data stored in the current data block to the selected data blocks under fast mode.

Abstract: A data storage device including a non-volatile memory and a micro-controller is provided. The non-volatile memory stores a firmware file. The micro-controller is coupled to the non-volatile memory, and performs an encryption procedure on the firmware file. The encryption procedure includes: using a first key and a first algorithm to encrypt the firmware file to generate a signature, using the first key and a second algorithm to scramble the signature to generate a scrambled signature, and attaching the scrambled signature to the firmware file.

Abstract: A data storage device including a non-volatile memory and a micro-controller is provided. The non-volatile memory includes a plurality of data blocks. The micro-controller selects one of the data blocks as a source block and another one of the data blocks as a destination block. Also, the micro-controller duplicates data in the source block to the destination block, and when the data is corrupted and unrecoverable, stores an unrecoverable-error bit corresponding to the data into the destination block.
