Abstract
A single integrated circuit flash memory controller is provided. When the CPU is operating, the operating time of the external ROM and all the flash memory devices are designed or programmed to function in an alternative manner, for example, the flash memory device will not be activated while the external ROM is operating to retrieve the program code. On the contrary, while data is being retrieved from the flash memory device, the CPU will be in a waiting status, in other words, the CPU does not function to retrieve the program code from the external ROM while the data is being retrieved from the flash memory device. Accordingly, this design makes it possible for the single integrated circuit flash memory control to accommodate required connections for connecting with the external ROM as well as all the flash memory device without the need to increasing pin terminals or the size of the integrated circuit package.
