Multi-function pins are provided for executing input of address bits and input/output of data bits. Address input enable signal and data I/O enable signal supplied from independent pins determine one between the address input and the data input/output to be performed by the multi-function pin. One of an address register, a data input register and a data output register provided for each multi-function pin operate in response to a combination of signal levels of the address input enable signal and the data I/O enable signal.
