A method and apparatus for control calibration of multiple memory modules within a memory channel is described. The method selects a memory channel from one or more memory channels coupled to a controller. Next, a memory module, coupled to the memory channel, is selected. A path delay is then determined for the selected memory module. The path delay includes a time interval for receipt of a data signal following issuance of a command by the controller to the selected memory module. Once determined, the path delay is stored, such that when the controller issues a command to a selected memory module, a controller receiver is enabled to capture a data signal following a time interval, as defined by the path delay, from issuance of the command. This process is repeated until a path delay is determined for each memory module of each memory channel coupled to the controller.
