    Abstract: The disclosed embodiments relate to a system that supports dynamic bursts to facilitate frequency-agile communication between a START 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.

    Abstract: Embodiments of an integrated circuit (IC) comprising frequency change detection circuitry are described. Some embodiments include first circuitry to generate a second clock signal based on a first clock signal, wherein the first clock signal has a first clock frequency, and wherein the second clock signal has a second clock frequency that is an integral multiple of the first clock frequency. The embodiments further include second circuitry to obtain samples by oversampling the first clock signal using the second clock signal. Additionally, the embodiments include third circuitry to detect a change in the first clock frequency based on the samples.
