The present disclosure provides a redundancy method for a flash memory device. The flash memory device comprises multiple storage areas in which at least one storage area is configured as a temporary storage area for redundant operations. The method comprises: performing redundant operations to a first set of pages stored in one of the plurality of storage areas in a cache to generate an intermediate result; storing the intermediate result to the storage area of the at least one temporary storage area for redundant operation from the cache; performing redundant operations to the (m+1)th set of pages stored in one storage area the redundant operation result of and the first set of pages stored in the at least one temporary storage area for redundant operation to produce a final result in the cache; storing the final result to the corresponding pages in the (m+1)th set of pages from the cache.

Memory device and redundancy method applied thereto

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.
