Abstract: A display driver circuit may include a revision controller for controlling a nonvolatile memory having instructions by which control data for controlling devices controlled by the display driver circuit are changed, and a drive controller for controlling the devices based on the instructions. The revision controller determines whether to perform a read operation to the instructions based on electrical power being applied to the display driver circuit, and transfers instruction signals, which are generated based on the determination to perform the read operation, to the driving controller.
