A memory system includes a plurality of memory devices having data terminals that are commonly connected to a memory controller. Each of the memory devices includes a data output circuit that outputs read data that is read from a memory cell array in response to a read command to the data terminal, and an output-timing adjustment circuit that adjusts an output timing of read data that is output from the data output circuit. The memory controller sets an adjustment amount of adjustment performed by an output-timing adjustment circuit such that delay times from when the read command is issued until when the read data is received match in the memory devices, by issuing a setting command to each of the memory devices.
