PROBLEM TO BE SOLVED: To correspond readily to modification in the command, the address and the I/O configuration of a memory macro functional block in a memory macro functional block embedded LSI. SOLUTION: A memory macro functional block 10 is physically divided into a memory core functional block 12 and an interface functional block 11. The interface functional block comprises a test circuit 111, a command decoder section 112 for a test, an address decoder section 113 for a test, and a memory core I/O circuit 114 to input a command and an address into the memory core functional block and to exchange data with the memory core functional block. The interface functional block further comprises a composition storage block 115 storing the memory capacity of the memory core functional block and the information on a memory core configuration, and the configuration control block 116 to control the data path and the address path of the memory core functional block based on stored information.
