An integrated circuit buffer device including a first port and a second port. The first port to receive data from a first integrated circuit memory device, and the second port to receive data from a second integrated circuit memory device. The integrated circuit buffer device further includes a multiplexer to output a data stream that includes the data received from the first integrated circuit memory device and the data received from the second integrated circuit memory device. In addition, the integrated circuit buffer device includes an interface including transmit circuitry to transmit the data stream to an integrated circuit controller device.
