By a controller managing the blocks of a FLASH memory within a data storage device, some of the blocks are pushed into a spare queue waiting to be allocated as data blocks or system blocks. When the number of blocks within the spare queue is lower than a clean threshold and any block within the spare queue has an erase count greater than an overused lower threshold, the controller performs a garbage correction operation with wear leveling between the different 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 flash memory control method","description":"A FLASH memory control technique with wear leveling between the different blocks of the FLASH memory.
