Claim:
1. A memory controller controlling a nonvolatile memory, the memory controller comprising: a read control unit configured to control the nonvolatile memory to perform reading, the nonvolatile memory having a first memory cell, second to fifth memory cells adjacent to the first memory cell, a first word line connected to gates of the first, the fourth and the fifth memory cells, a second word line adjacent to the first word line and connected to a gate of the second cell, and a third word line adjacent to the first word line and connected to a gate of the third memory cell; and a decoding unit configured to determine whether or not influence of at least one of the second to the fifth memory cells on the first memory cell is large, and in a case where it is determined that the influence of the at least one of the second to the fifth memory cells on the first memory cell is large, to obtain likelihood information of the first memory cell based on a reading result from the first memory cell and a reading result from the at least one of the second to the fifth memory cells.
