A memory interface circuit for read operations is described. The circuit includes one or more controller circuits, one or more read data delay circuits for providing CAS latency compensation for byte lanes. In the system, control settings for the read data delay circuits for providing CAS latency compensation are determined and set using controller circuits according to a dynamic calibration procedure performed from time to time. In the system, determining and setting the control settings for the read data delay circuits for providing CAS latency compensation is performed independently and parallely in each of a plurality of byte lanes.
