Abstract: A data storage device includes a memory and a controller. The controller is configured to, in response to a transition from a low power state to an active state, load runtime data to a volatile memory of the controller from a memory of a device coupled to the controller via an interface and, concurrently with loading the runtime data from the memory of the device to the volatile memory of the controller, load other data from the non-volatile memory to the volatile memory of the controller.

Abstract: In one embodiment, a memory system is provided comprising at least one memory die, a sensor configured to sense an average amount of power consumed by the memory system over a time period, and a controller. The controller is configured to maintain a token bucket that indicates an amount of power currently available for memory operations in the at least one memory die and is further configured to reduce a number of tokens in the token bucket by an amount of power consumed over the time period as indicated by the average amount of power sensed by the sensor over the time period.
