Abstract:
1. A RAM-incorporated driver that drives a display section based on still-image data and moving-image data, the RAM-incorporated driver comprising: a first port through which the still-image data or a given command is input from a microprocessor unit that is external to the RAM-incorporated driver; a second port through which the moving-image data, which is transferred serially over a serial transfer line from the microprocessor unit that is external to the RAM-incorporated driver, is input as a differential signal; a reception circuit which differentially amplifies the differential signal input from the second port and creates the moving-image data in a parallel state; a RAM which stores the still-image data that was input through the first port and the moving-image data that was created by the reception circuit; a first control circuit which controls writing or reading of the still-image data or the moving-image data that has been input separately through the first port or the second port, with respect to the RAM; and a second control circuit that, independently of the first control circuit, controls the reading of display data of the still-image data or moving-image data that has been stored in the RAM, and drives the display section to display, wherein the RAM includes memory cells each of which has two input ports through which the moving-image data and the still-image data are input separately and an output port through which data stored in the memory cell is output.
