Abstract: A host controller apparatus for determining information related to a time shift for transmitting instructions on a command and address bus includes an interface for transmitting a plurality of instruction signals to a memory module via the command and address bus and for receiving a loopback feedback signal from the memory module. The host controller apparatus further includes a control module configured to transmit the plurality of instruction signals to the memory module via the command and address bus. The control module is configured to receive the loopback feedback signal from the memory module. The loopback feedback signal includes a looped-back composite version of the plurality of instruction signals. The control module is configured to determine the information related to the time shift for transmitting instructions on the command and address bus based on the loopback feedback signal.
