Abstract
A method and system for phasing power-intensive operations is disclosed. A non-volatile storage device controller detects a power reset. The controller is in communication with non-volatile memories in the non-volatile storage device. In response to detecting a power reset, the controller determines a current consumption necessary to reset the non-volatile memories in the non-volatile storage device. The controller simultaneously resets all of the non-volatile memories when the determined current consumption is less than a current consumption threshold. If the determined current consumption is greater than the current consumption threshold, the controller resets a first subset of the plurality of non-volatile memories, and after a predetermined delay, resets a second subset of the non-volatile memories. Therefore, a power-intensive operation may be performed without exceeding a current consumption threshold by dividing the operation into a sequence of steps that do not exceed the threshold.
