An image processing apparatus capable of performing a refresh operation without causing a drop in performance, an increase in cost, or damage to the apparatus. The apparatus further being capable of achieving a reduction in power consumption, and being provided with a memory I/F circuit able to not only refresh, for example, four DRAM modules simultaneously, but also capable of refreshing two DRAM modules at a same timing, then refreshing the remaining two DRAM modules simultaneously at a next timing, or refreshing the four DRAM modules one by one in order based on given refresh control data, and controlling the timing of the refresh operation for each divided DRAM module.
