The FLASH memory includes a plurality of blocks wherein each of the blocks includes a plurality of pages. The controller is coupled to the FLASH memory and utilized to execute a garbage-collection process on the FLASH memory according to a number of spare blocks in the FLASH memory and a number of inefficient blocks where most of the pages are spare in the FLASH memory. The garbage-collection process is utilized for merging at least two inefficient blocks to release at least one spare block from the inefficient blocks."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data storage device and operating method","description":"A data storage device includes a FLASH memory and a controller.
