PURPOSE:To speed up access by allowing a processor to fetch two data corresponding to a specified address and a next address or specified address at the same time. CONSTITUTION:A storage device is divided into an even address storage device 5 and an odd address storage device 6. When the processor 1 fetches data corresponding to an odd and an even address at the same time, the address part excluding the least significant digit bit of the specified address is supplied to the device 5 or 6 having data corresponding to the odd or even address. Then an adder 41 adds 1 or 0 to the address part and supplies the result to the device 5 or 6 having odd or even addresses. Thus, two data corresponding to the same address part or two data corresponding to different address parts are obtained at the same time. Consequently, the access is speeded up.
