  • Publication number: 20230106072
    Abstract: The disclosed embodiments relate to a system that supports dynamic bursts to facilitate frequency-agile communication between a memory controller and a memory device. During operation, the system monitors a reference clock signal received at an interface between the memory device and the memory controller. Upon detecting a frequency change in the reference clock signal from a fullrate to a subrate, the interface operates in a burst mode, wherein data is communicated through bursts separated by intervening low-power intervals during which portions of the interface are powered down.
