Systems and methods are disclosed for managing the peak power consumption of a system, such as a non-volatile memory system (e.g., flash memory system). The system can include multiple subsystems and a controller for controlling the subsystems. Each subsystem may have a current profile that is peaky. Thus, the controller may control the peak power of the system by, for example, limiting the number of subsystems that can perform power-intensive operations at the same time or by aiding a subsystem in determining the peak power that the subsystem may consume at any given time.
