    Abstract: The flash memory device includes a control logic circuit and a bit level conversion logic circuit. The control logic circuit programs first through Nth bits of data in a memory cell array of the N-bit MLC flash memory device or reads the first through Nth bits of the data from the memory cell array in response to one of a program command and a read command. The bit level conversion control logic circuit, after the first through Nth bits of the data are completely programmed or read, programs or reads an (N+1)th bit of the data in response to a control signal. The bit level conversion control logic circuit converts voltage levels of voltages, which are used for programming or reading the first through Nth bits of the data, to program or read for 2N cell distributions of 2N+1 cell distributions corresponding to the (N+1)th bit of the data and then programs or reads for other 2N cell distributions.

    Abstract: A method may be provided to detect and correct data errors in a data system where a data message has been encoded with outer parity bits based on the data message using an outer encoding technique to provide an outer codeword and with inner parity bits based on the outer codeword using an inner encoding technique different than the outer encoding technique to provide an inner codeword. The method may include using the inner parity bits and an inner decoding technique corresponding to the inner encoding technique to perform inner decoding of the inner codeword. Responsive to performing inner decoding of the inner codeword without error, the data message may be extracted from a result of inner decoding the inner codeword without using the outer parity bits to decode the result of inner decoding the inner codeword. Related systems are also discussed.
