PURPOSE:To reduce man-days required for assembling and inspecting by selecting a corresponding signal according to a control signal to supply to the terminal of a different signal, decoding an address designating signal, and supplying to an operating state setting terminal in the terminals of the same signal. CONSTITUTION:A CPU generates the control signal SC corresponding to the type of a RAM 2, in a selection circuit SEL 4, the corresponding signal is selected according to the signal SC to apply to the terminal of the different signal. A decoder DEC 3 decodes the address designating signal AS according to the signal SC and applies to the operating state measuring terminal of the terminals of the same signal. Accordingly, the SEL 4 and the DEC 3 operate in response according to the signal SC and the signal corresponding to the type of the RAM 2 is selected and supplied to the terminal of the same number and different signal. At the same time, the signal corresponding to the type of the RAM 2 of the address designating signals is decoded and applied to the terminal for the operating state setting. Thereby, since the labor for selecting and setting is not required, the number of the processes for assembling and inspecting is reduced.
