<p>PURPOSE:To reduce the power consumption of an equipment using a DRAM at a suspend time. CONSTITUTION:In an information processor using the DRAMs to both of a main memory 1 and a video memory 5, this device is constituted so that a refresh signal outputted from a main memory controller 2 at the suspend time of the device is imparted to both of the main memory 1 and the video memory 5 through a main memory 1/F 8. For the purpose, this device is provided with a refresh signal switching circuit 11 switching the refresh signal supplied to a video memory I/F 10 to any I/F of the main memory I/F 8 and the video memory I/F 9 selectively and a switching control circuit 12 controlling the circuit 11. Further, a power source stopping circuit 13 stopping the supply of power to a display controller 4 at the suspend time is provided.</p> |
