Data storage device and data processing method

A data storage device, comprising:

• a memory device, comprising a plurality of memory chips and each memory chip comprising a plurality of memory blocks;
• and
• a memory controller, coupled to the memory device and arranged to access the memory device, wherein the memory controller is further arranged to configure a plurality of first memory block to receive data from a host device, the first memory blocks form at least a first superblock, the first superblock comprises a first predetermined number of first memory blocks located in different memory chips,
• wherein when an amount of data stored in the first memory blocks reaches a specific value, the memory controller is arranged to move the data from the first memory blocks to a plurality of second memory blocks in a predetermined procedure,
• wherein the second memory blocks form at least a second superblock and the second superblock comprises a second predetermined number of second memory blocks located in different memory chips, and
• in the predetermined procedure, the data stored in the first memory blocks is sequentially written into the second memory blocks, wherein the data stored in two adjacent logical pages in the first superblock is written in two second memory blocks located in different memory chips.
