Abstract

In one embodiment, a method for power management includes receiving one or more state signals, each of the one or more state signals indicating whether a respective sub-block of a memory controller is idle or active, and determining whether to place the memory controller in an idle state or an active state based on the one or more state signals. The method also includes eating pulses of an input clock signal to produce a reduced-frequency clock signal if a determination is made to place the memory controller in the idle state, wherein the reduced-frequency clock signal is output to the memory controller. The method further includes passing the input clock signal to the memory controller if a determination is made to place the memory controller in the active state.
