Abstract
The present invention provides a flash memory controller, wherein the flash memory controller includes a read-only memory, a microprocessor and a decoder, wherein the read-only memory is configured to store a program code, and the microprocessor is configured to execute the program code to access a flash memory module. In the operations of the flash memory controller, when the flash memory controller is powered on, the microcontroller reads a plurality of pages of a specific block of the flash memory module, and the decoder decodes data of the plurality of pages. When any one of the pages cannot be decoded successfully, the microcontroller seals the specific block, and increase a priority of the specific block for quality detection or garbage collection.
