Abstract
A system and method for calibrating memory using credit-based segmentation control is disclosed. A memory and a memory controller coupled thereto. The memory controller includes a calibration circuit configured to calibrate a data strobe signal conveyed to/from the memory. The calibration may be subdivided, in time, into a number of segments. The memory controller also includes a credit circuit configured to provide a condition code to the calibration circuit. The condition code may be indicative of an amount of time a request has been pending, or how many request are pending. If the condition code indicates that a request has been pending for more than a certain amount of time, the calibration may be terminated.
