Abstract
An arbitration circuit to arbitrate an issue between a read/write command and a scan command and a display driver integrated circuit including the arbitration circuit. The arbitration circuit includes a latch unit having a first latch circuit that latches and outputs a first signal related to a scan command and a second latch circuit that latches and outputs a second signal related to a read/write command, wherein the latch unit resets outputs of the first latch circuit and/or the second latch circuit in response to a ready signal related to a memory operation, and a maintaining unit to receive outputs of the first latch circuit and the second latch circuit, to generate a first internal signal to activate a scanning operation and a second internal signal to activate a reading/writing operation, maintain the first internal signal and the second internal signal, and to selectively activate the first internal signal or the second internal signal by changing the state of at least one of the first internal signal and second internal signal in response to the reset operation.
