Abstract
A memory management control device and a memory management control method capable of preventing run away of an image processing apparatus caused by a rewrite to a memory, are provided. In rewriting a program stored in a flash memory 402 of a controller 400 included in an image processing apparatus, an operating state detector 500 detects the operating state of the image processing apparatus and transmits the detection result to an external apparatus 9. On the basis of this detected operating state, the external apparatus 9 performs rewrite control for the flash memory 402. If the image processing apparatus is in operation, or is in an intermediate state, an abnormal state, or a wait state, a rewrite action is executed after the state is canceled.
