| 1. An integrated circuit memory device comprising:
an output driver;
a first register to store a value representative of a drive strength setting of the output driver, wherein the value is determined
based on a topography of a plurality of integrated circuit memory devices, including the integrated circuit memory device,
that are coupled to a bus; and
a transmitter circuit including the output driver to output data using the drive strength setting and synchronously with respect
to an external clock signal.
