Data driving apparatus for display and driver thereof

A data driving apparatus for a display device, comprising:

• a memory configured to store operation data, and provide the operation data through a routing line;
• a first driver coupled to the memory through the routing line, and configured to provide a first read command to the memory and receive the operation data provided in response to the first read command, in a first operation period;
• one or more second drivers configured to share the memory with the first driver through the routing line, and receive the operation data shared through the routing line in the first operation period;
• and
• a request line shared by the first driver and the one or more second drivers,
• wherein the first driver and the one or more second drivers generate a request command when a fail occurred in the received operation data, and share the request command with the request line,
• the first driver provides a second read command to the memory in response to the request command, and
• the driver having generated the request command, among the first driver and the one or more second drivers, receives the operation data corresponding to the second read command.

A driver of a data driving apparatus for a display device, comprising:

• a checksum determination unit configured to share operation data of a memory with one or more other drivers through a routing line, receive the operation data through the routing line in a first operation period, and provide a determination signal indicating a result obtained by determining a fail of the operation data;
• and
• a request driving circuit configured to generate a request command in response to the determination signal, and drive the request command to a request line shared with the one or more other drivers,
• wherein the driver receives the operation data shared by the routing line in response to the request command in a second operation period following the first operation period.
