1. A memory controller comprising:
storage circuitry to store a first programmed value and a second programmed value;
a first timing signal generator to generate a first timing signal having a phase offset relative to a first clock signal in
accordance with the first programmed value;
a second timing signal generator to generate a second timing signal having a phase offset relative to the first clock signal
in accordance with the second programmed value; and
output driver circuitry to output, from the memory controller, an address value in response to the first timing signal and
a control value in response to the second timing signal, the address value and control value constituting portions of a first
memory access request.
