Abstract
The present invention provides a flash memory controller including an artificial intelligence (AI) module and a microprocessor. In the operations of the flash memory controller, the AI module receives data from a host device, and determines if the data is important data or unimportant data to generate a determination result. The microprocessor is configured to write the data into a flash memory module according to the determination result, wherein the flash memory module comprises a plurality of first blocks and a plurality of second blocks, and quantity of bits stored in each memory cell within the first blocks is lower than quantity of bits stored in each memory cell within the second blocks. When the determination result indicates that the data is the important data, the microprocessor only stores the data into at least one of the first blocks.
