description A semiconductor integrated circuit device of the present invention connected to a memory in which display data for a display device is stored, and is adapted to read out the display data from the memory to transfer the same to the display device, the semiconductor integrated circuit device comprising: a display data buffer for holding the display data; a memory controller for prefetching the display data in page-size units of the memory to cause the same to be held by the display data buffer and, upon completing prefetching of one page, closing the page to cause the memory to shift into a power saving mode; and a display device controller for transferring the display data held in the display data buffer to the display device.
