    摘要： A method for managing a memory controller comprising selecting a low-power state from a plurality of low-power states. The method further comprises transitioning to the low-power and entering the low-power state when the transition is complete, provided a wake-event has not been received. An apparatus comprises a controller configured to select a power state for transition, a state-machine configured to execute steps for transitions between power states of a memory controller connected by a bus to a memory, a storage configured to store at least one context, and a context engine configured to stream, at the direction of the state-machine engine, the at least one context to the memory controller. Streaming comprises communicating N portions of context data as a stream to N registers in the memory controller. A context comprises a plurality of calibrations corresponding to a state selected for transition.
