More Information
Summary:A memory device with high reliability is provided, which includes a flash memory and an error-correcting device. The flash memory is suitable for storing at least a first codeword. The error-correcting device reads the first codeword from the flash memory with read-retry several times, and getting a set of soft information. Next, the error-correcting device uses the set of soft information for the first codeword to process a first error correction code processing, and then generating a second codeword. And then, the error-correcting device processes a second error correction code processing for the second codeword, and then recovering and outputting the user data. Thus, the memory device can improve the accuracy of data access.
