Abstract

A data storage device includes a memory device and a memory controller. The memory device includes multiple memory blocks. The memory controller is coupled to the memory device and is configured to access the memory device. In a garbage collection procedure, the memory controller is configured to select multiple spare memory blocks as destination memory blocks and move valid data stored in at least one source memory block into the destination memory blocks. In the garbage collection procedure, the memory controller is further configured to determine an attribute of each valid data and determine which destination memory block to move the valid data into according to the corresponding attribute. Valid data having the same attribute is moved to the same destination memory block.
