Title:
ADAPTIVE POWER REGULATION METHODS AND SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2018/038802
Kind Code:
A3
Abstract:
Adaptive power regulation methods and systems are disclosed. In one aspect, one or more process sensors for memory elements are provided, which report information relating to inherent speed characteristics of sub-elements within the memory elements. Based on this reported information, a controller ascertains an appropriate power level to insure a proper data retention voltage (DRV) is applied on voltage rails by a power management unit (PMU) circuit. By using the proper DRV based on the speed characteristics of the sub-elements within the memory elements, power conservation is achieved.
