Abstract
A first rank includes a plurality of first semiconductor memory devices, and a second rank includes a plurality of second semiconductor memory devices. The command/address signal lines are shared by a controller, the first rank, and the second rank, and the data lines are shared by the controller, the first rank, and the second rank. When performing a data movement operation of moving data between the first rank and the second rank, the controller applies a shift read command to one of the first rank and the second rank through the command/address signal lines and applies a normal write command or a shift write command to another of the first rank and the second rank through the command/address signal lines after a time corresponding to a value obtained by subtracting the value of the write latency from the value of the read latency.
