Abstract
Disclosed herein are methods, apparatuses and systems related to adjusting memory operations according to a usage pattern or a contextual parameter. The apparatus may be configured to track an operating measure associated with operating in an active operating mode and a switching measure associated with a transition into a reduced power mode. Based on the tracked measures, the apparatus may be configured to dynamically adjust a delay used in subsequently transitioning into the reduced power mode.
Claims20
A memory device, comprising:
- a host interface configured to receive external communications from a host device;
- a memory array configured to store and provide access to data;
- and
- a memory controller operably coupled to the memory array and configured to:
- track a control timer for measuring a lapsed idle time since a targeted event;
- transition from an active operating mode to a reduced power mode when the lapsed idle time reaches a control time threshold, wherein the reduced power mode includes reducing or removing power consumed by the memory array, one or more components within the memory controller, or a combination thereof;
- track an operating measure based on measuring a duration for the active operating mode;
- track a switching measure based on counting the transition between the active operating mode and the reduced power mode;
- and
- dynamically adjust the control time threshold based on comparing the operating measure and the switching measure, wherein the control time threshold is adjusted to balance the operating measure and the switching measure.
A method of operating a memory device, the method comprising:
- tracking a control timer for measuring a lapsed idle time since a targeted event at the memory device;
- transitioning from an active operating mode to a reduced power mode when the lapsed idle time reaches a control time threshold;
- tracking an operating measure based on measuring a duration for operating the memory device in the active operating mode;
- tracking a switching measure based on counting the transition into and/or out of the active operating mode;
- and
- dynamically adjusting the control time threshold based on the operating measure and the switching measure.
A memory device, comprising:
- a memory array configured to store and provide access to data;
- and
- a logic operably coupled to the memory array and configured to:
- track an operating measure representative of a duration for operating the memory device in an active operating mode;
- track a switching measure based on counting a transition between the active operating mode and a reduced power mode that operates the memory array or another component within the memory device at a lower power state;
- and
- dynamically adjust a control time threshold based on the operating measure and the switching measure, wherein the control time threshold represents a threshold for an idle duration used for transitioning the memory device into the reduced power mode.
