Abstract:
A data storage device includes a memory device and a controller. The memory device includes multiple memory blocks. The memory blocks include single-level cell blocks and multiple-level cell blocks. The controller is coupled to the memory device. When the controller executes a predetermined procedure to write data stored in the single-level cell blocks into the multiple-level cell blocks, the controller is configured to determine whether a valid page count corresponding to each single-level cell block is greater than a threshold, and when the valid page count corresponding to more than one single-level cell block is greater than the threshold, the controller is configured to execute a first merge procedure to directly write the data stored in the single-level cell blocks with the valid page count greater than the threshold into one or more of the multiple-level cell blocks.
