In an information processing device 30 having engaged in a detachable manner with, for processing, via an external bus 37, 47 in a second data width, a first game cartridge 20 housing first memory 22 in a first data width, or a second game cartridge 40 being partially different in shape from the first game cartridge 20 and housing second memory 42 in the second data width, a shape discriminator 35 discriminates between the first and second game cartridges 20, 40, and a central processing unit accesses the second memory 42 in a multiplex bus mode and the first memory 22 in a normal mode. A second storage device 48 housed in the second game cartridge 40 includes the memory 42 for recording data which causes the information processing device 30 to execute processing, and a multiaccess control part 44 for controlling address and data exchange in a time-sharing manner. The second memory 42 is driven by a first voltage of 3.3V, while the first memory 22 by a second voltage of 5V. The information processing device 30 supplies either of 5V or 3.3V to the memory 22, 42 depending on the cartridge type currently engaged. The central processing unit 360 is activated in a mode corresponding to the voltage whichever supplied.
