Access control is achieved in consideration of write training. Masters issue access requests including a read request and a write request. A memory controller accesses memory in response to the access requests issued by the maters. A central bus-control system controls the output of the access requests issued by the masters to the memory controller. A training circuit conducts training on the memory while the access to the memory is stopped. The central bus-control system further controls the execution of the training on the memory. During the training, the central bus-control system suppresses the output of the read request to the memory controller from among the access requests issued by the masters.
