Abstract
Methods and systems are disclosed for calibrating, by a memory interface system, an interface with dynamic random-access memory (DRAM) using a dynamically changing training clock. Techniques disclosed comprise receiving a system clock having a clock signal at a first pulse rate. Then, during the training of the interface, techniques disclosed comprise generating a training clock from the clock signal at the first pulse rate, the training clock having a clock signal at a second pulse rate, and sending, based on the generated training clock, command signals, including address data, to the DRAM.
