A data storage device includes a memory device and a memory controller. When a sub-region of the memory device is selected based on a predetermined rule to perform a data rearrangement procedure, the memory controller determines whether the selected sub-region is a system data sub-region. When determining that the selected sub-region is not a system data sub-region, the memory controller performs the data rearrangement procedure on the selected sub-region to move data corresponding to logical addresses belonging to the selected sub-region to a memory space of the memory device having continuous physical addresses, and when determining that the selected sub-region is a system data sub-region, the memory controller does not perform the data rearrangement procedure on the selected sub-region.

Data processing method for improving continuity of data corresponding to continuous logical addresses as well as avoiding excessively consuming service life of memory blocks and the associated data storage device

A data storage device includes a memory device and a memory controller. The memory controller uses a first predetermined memory block as a buffer to receive data from a host device. In response to a write command received from the host device, the memory controller determines a sub-region corresponding to the write command, determines whether the sub-region is a hot-write sub-region according to a write count corresponding to the sub-region and accordingly determines whether to use a second predetermined memory block as another buffer to receive data from the host device. When the memory controller determines that the sub-region corresponding to the write command is a hot-write sub-region, the memory controller writes the data into the second predetermined memory block. When the memory controller determines that the sub-region is not a hot-write sub-region, the memory controller writes the data into the first predetermined memory block.

Data processing method for efficiently processing data stored in the memory device by splitting data flow and the associated data storage device

A data storage device includes a memory device and a memory controller. The memory controller uses a first predetermined memory block as a buffer to receive data from a host device. In response to a write command received from the host device, the memory controller determines a sub-region corresponding to the write command, determines whether the sub-region is a system data sub-region and accordingly determines whether to use a second predetermined memory block as another buffer to receive data from the host device. When the memory controller determines that the sub-region corresponding to the write command is a system data sub-region, the memory controller writes the data into the second predetermined memory block. When the memory controller determines that the sub-region corresponding to the write command is not a system data sub-region, the memory controller writes the data into the first predetermined memory block.
