  • Patent number: 11804167
    Abstract: A display driver integrated circuit (IC) includes a logic module sequentially issuing read commands including a first read command, a second read command succeeding the first read command, and a third read command succeeding the second read command, and memory modules connected in series with each other. A first memory module is connected to the logic module and is the closest memory module to the logic module. The first memory module receives the read commands, provide the first read command to a first memory of the first memory module, read first image data from the first memory in response to the first read command, and provide the first image data and first remaining read commands among the read commands to a second memory module which is connected to the first memory module and farther than the first memory module from the logic module.
