Abstract
A semiconductor memory system may include a read data manager configured to store data read from a memory device, a likelihood value mapper configured to map likelihood values to the data output from the data manager and output mapping data, and a decoder configured to perform low density parity check decoding on the mapping data by using a parity check matrix. The parity check matrix may be a k*N×M matrix including k*N×M submatrices, where k, N and M are independently an integer equal to or greater than 2.
