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.

摘要:
A method for detecting and decoding a signal in a communication system based on Multiple-Input Multiple-Output (MIMO)-Orthogonal Frequency Division Multiplexing (OFDM). A signal is received through multiple receive antennas. A decision error occurring at a symbol decision time is considered and a symbol is detected from transmitted symbols. Original data transmitted from the detected symbol is recovered. The performance of a coded bit system can be significantly improved using a new equalization matrix G considering a decision error.
