ABSTRACT:
The present invention provides a RAM-incorporated driver that enables the writing of moving-image data to a RAM simultaneously with the writing of still-image data to a RAM, at a reduced energy consumption. The RAM incorporated X-driver IC receives still-image data from an MPU and moving-image data that is input by a separate system through a high-speed serial transfer line in accordance with the LVDS standard. An LVDS reception circuit suppresses the consumption of a steady current by which the differential input receiver operates, based on a data validation signal that becomes active when transfer data on the high-speed serial data transfer line from the MPU becomes valid. The still-image data and moving-image data that is received by separate systems is written to a RAM through first and second bus lines, respectively. Reading of still-image data and moving-image data, which is stored in a RAM, as display data is controlled by a display address control circuit.
