  • Flash memory device error correction code controllers and related methods and memory systems
    Patent number: 8788905
    Abstract: An ECC controller for a flash memory device storing M-bit data (M: a positive integer equal to or greater than 2) includes an encoder and a decoder. The encoder generates first ECC data for input data to be stored in the flash memory device using a first error correction scheme and generates second ECC data for the input data using a second error correction scheme. The input data, the first ECC data, and the second ECC data are stored in the flash memory device. The decoder calculates the number of errors in data read from the flash memory device and corrects the errors in the read data using one of the first ECC data and the second ECC data selectively based on the number of the errors.
