A system comprises a controller device, an integrated circuit buffer
device and a first and second memory device. A first plurality of signal
lines is coupled to the controller device. A second plurality of signal
lines is coupled to the first memory device and the integrated circuit
buffer device. The second plurality of signal lines carries first address
information from the integrated circuit buffer device to the first memory
device. A third plurality of signal lines is coupled to the first memory
device and the integrated circuit buffer device. The third plurality of
signal lines carries first control information from the integrated
circuit buffer device to the first memory device. A first signal line is
coupled to the first memory device and the integrated circuit buffer
device. The first signal line carries a first signal from the integrated
circuit buffer device to the first memory device. The first signal
synchronizes communication of the first control information from the
integrated circuit buffer device to the first memory device.
