Systems and methods for reducing performance state change latency
Abstract:
A method and apparatus for performing performance state changes are disclosed. A power management circuit may be configured to receive requests for changes to first and second performance states for at least at least one memory of a plurality of memories. In response to a determination that a change to the first performance state is in progress, when the request to change to the second performance state is received, the power management controller may send a notification to a controller coupled to the memories. The controller may halt scheduling of memory interface calibration operations for the at least one memory based on the notification.
