A switching power-supply apparatus and a switching power supply circuit in which a feedback signal is input from a feedback circuit to a feedback terminal of a switching control IC includes a capacitor and a Zener diode connected between the feedback terminal and a ground terminal. The Zener diode is a selectively connected external circuit. A voltage of the feedback terminal during an overcurrent operation changes depending on whether or not the external circuit is present. A return / latch determination circuit detects the voltage of the feedback terminal to switch between an automatic return system and a latch system in an overcurrent operation state.

The invention reduces the pin terminal number of a controller that in parallel or simultaneously accesses a synchronous memory and an asynchronous memory. When a column address is latched to an SDRAM, immediately after that, access to FLASH is started, and a shared bus controller outputs the write / read address with respect to FLASH on the address bus. Then, after the end of data transfer on the data bus, either the shared bus controller outputs the write data, or FLASH can output the read data on the data bus by means of a strobe signal. Then, the input of address is established by FLASH, and, as the shared bus controller asserts a strobe signal, either FLASH fetches the write data on the data bus, or the shared bus controller fetches the read data on the data bus.
