PURPOSE:To prevent the malfunction of a system utilizing a memory device by providing a delaying circuit so that chip select information is delayed by a prescribed time, and thereafter, inputted to a data output control circuit. CONSTITUTION:A delaying circuit 12 is provided between a chip select input buffer circuit 8 and a data output controlling circuit 9. As a result, the time when a chip select information is inputted to the data output control circuit 9 can be matched with a delay time when memory information is outputted from a row selector 6. Accordingly, even if each new address information and chip select information are given simultaneously to an address input terminal 1 and a chip select input terminal 7 from a floating state of an output terminal, the memory information corresponding to the previous address information is not outputted, the memory information corresponding to the new address information is outputted to a data output terminal 11, and the malfunction of a system can be prevented. |
