摘要
Methods and apparatus are provided for detection and decoding in flash memories using a correlation of neighboring bits or errors in neighboring bits. Data from a flash memory device is processed by obtaining one or more read values for a plurality of bits in a given page of the flash memory device; converting the one or more read values for the plurality of bits to a reliability value for a bit among said plurality of bits based on a probability that a data pattern was written to the plurality of bits given that a particular pattern was read from the plurality of bits; and decoding the bit in the page using the reliability value. The probability that the data pattern was written to the plurality of bits given that the particular pattern was read from the plurality of bits is obtained from one or more tables.
