In a system having a synchronous flash memory device which shares a system bus with a synchronous random access memory device, the synchronous random access memory device is set to refresh mode before a program or erase operation is performed in the synchronous flash memory device, thereby preventing the program and erase operations of the synchronous flash memory device from affecting the operation of, or data stored in, the synchronous random access memory device. After the program or erase operation is completed, the synchronous random access memory device is placed back in normal mode.
