Abstract: A method for controlling access operations of a flash memory includes: receiving first source data from a host; generating a plurality of first scrambled signals according to a plurality of pseudo random sequences and the first source data; obtaining a plurality of transmission powers of the first scrambled signals; and selecting a target scrambled signal from the first scrambled signals according to the transmission powers for storing to the flash memory. An associated flash memory device and an associated flash memory controller are also provided.
