Abstract
An image memory controller having a first address signal generating unit generating a first address signal in response to a state signal representing the operational state of a printer. The first address signal corresponds to a location in an image memory. A second address signal generating unit generates a second address signal for refreshing the image memory and a third address signal generating unit generates a third address signal used for rewriting at least part of data stored in the image memory. An address signal selector selectively delivers any of the first, second, and third address signals to the image memory.
