Abstract: A method is described. The method includes configuring first register space to establish ODT values of a data strobe signal trace of a DDR data bus. The method also includes configuring second register space to establish ODT values of a data signal trace of the DDR data bus. The ODT values for the data strobe signal trace are different than the ODT values for the data signal trace. The ODT values for the data strobe signal do not change when consecutive write operations of the DDR bus write to different ranks of a same DIMM.
