PROBLEM TO BE SOLVED: To suppress a noise generated in transferring data to memory.SOLUTION: A memory controller C comprises: a writing part 6 that writes transfer data in memory; and a reading part 7 that reads the data from the memory. The writing part 6 includes a replacement unit 6b that, when the sequence pattern of "1" and "0" of a bit string constituting the data to be transferred to a signal line DL is a target pattern set as a replacement target, replaces the bit string with a replacement bit string in which noise is suppressed before writing the data to the memory. The reading part 7 includes a restoration unit 7b that restores an initial bit string from the replacement bit string read out from the memory.SELECTED DRAWING: Figure 2 |
