Abstract:
Systems and methods are disclosed for asynchronous management of access requests to control power consumption. In some cases, by asynchronously managing power within a system, multiple dies of a NVM can simultaneously draw current in order to match the power demand. In particular, an arbiter of the system can receive multiple requests to draw current, where each request may be associated with a different die of the NVM. In some embodiments, the arbiter can determine the servicing order using the time of arrival of the request (e.g., a first-in, first-out scheme). In other embodiments, the arbiter can simultaneously service multiple requests so long as the servicing of the multiple requests does not exceed a power budget.
