Cooperative Writes over the Address Channel of a Bus

A method of communicating over a bus is disclosed. The bus includes a write address channel, a write channel, and a read address channel. The method includes sending an address from a sending device to a receiving device via the write address channel. The method further includes concurrently sending a portion of a payload to the receiving device via the write channel and another portion of the payload to the receiving device via the read address channel. When sending multiple sequential portions of the payload via the bus concurrently, the sending device is configured to give data ordering preference to the write channel over the read address channel by sending a first sequential portion of the multiple sequential portions via the write channel and sending a subsequent sequential portion of the multiple sequential portions via the read address channel.
