Abstract:
A self-test method of a flash memory device includes: generating input data; encoding the input data to generate an error correction code; utilizing the input data and the error correction code to simulate to read a page of a flash memory of the flash memory device to generate soft information; and decoding the soft information to generate a decoding result.
