METHOD AND APPARATUS FOR READING DATA STORED IN FLASH MEMORY BY REFERRING TO BINARY DIGIT DISTRIBUTION CHARACTERISTICS OF BIT SEQUENCES READ FROM FLASH MEMORY

摘要

A method for reading data stored in a flash memory includes at least the following steps: controlling the flash memory to perform a plurality of read operations upon a plurality of memory cells included in the flash memory; obtaining a plurality of bit sequences read from the memory cells, respectively, wherein the read operations read bits of a predetermined bit order from the memory cells by utilizing different control gate voltage settings; and determining readout information of the memory cells according to binary digit distribution characteristics of the bit sequences.
