A card host LSI includes M card host I/Fs for N-bit card modules, and M card bus terminals. A bridge circuit sets coupling relationship of signal lines so that a card host I/F corresponding to a card bus coupled to an (M×N)-bit card module and the other card host I/F(s) operate in conjunction with each other to control the card module, when an enable signal indicates the (M×N)-bit mode.
