Abstract: A data protecting method and a memory storage device are provided. The data protecting method includes reading a first string from the rewritable non-volatile memory module to obtain a data string; performing a decoding operation based on the data string to obtain block information corresponding to a plurality of physical erasing units; inputting the block information to an error checking and correcting (ECC) circuit of the memory storage device to generate a second string; and storing the second string into the rewritable non-volatile memory module.

Abstract: A memory address management method, a memory controller, and a memory storage device are provided. The memory address management method includes: obtaining memory information of a rewritable non-volatile memory module and formatting logical addresses according to the memory information to establish a file system, such that an allocation unit of the file system includes a lower logical programming unit and an upper logical programming unit. Here, the memory information includes a programming sequence, the allocation unit starts with the lower logical programming unit and ends with the upper logical programming unit, and an initial logical address of a data region in the file system belongs to the lower logical programming unit. Accordingly, an access bandwidth of the memory storage device is expanded.

Abstract: A memory storage device and a repairing method thereof are provided. The memory storage device has a rewritable non-volatile memory module having multiple physical units. The physical units include at least one backup physical unit which is configured to be accessed only by a specific command set and stored with at least one customized data. The method includes receiving a specific read command from a host system for reading the backup physical unit and transmitting the customized data therein to the host system when the memory storage device is capable of receiving and processing commands from the host system, the specific read command belongs to the specific command set; and writing the customized data from the host system into a corresponding physical unit to restore the memory storage device to a factory setting when receiving the writing command from the host system for writing the customized data.
