Test functions are expanded by adopting a self test part, and circuit scale is reduced by adding the self test part. A semiconductor integrated circuit includes a memory that includes plural memory banks and is accessed by specifying a bank address, an X address, and a Y address, and a self-test part that tests the memory in response to commands. The self-test part has an address counter covering plural addressing modes that are different in the updating of X addresses, Y addresses, and bank addresses. A variety of addressing modes provided expand BIST-based test functions.
