Abstract
Methods that can manage power for memory subsystems are provided. One method includes providing power to a set of memory devices via a set of power modules, determining a first amount of power being consumed by the set of memory devices, and in response to a predetermined event, modifying a second amount of power provided to the set of memory devices via a set of spare power modules. Systems and apparatuses that can include, perform, and/or implement the method are also provided.
Claims20
A system, comprising:
- a set of memory devices;
- a set of power modules that provide power to the set of memory devices;
- and
- a set of spare power modules coupled to the set of memory devices and configured to controllably provide supplemental power to the set of memory devices.
An apparatus, comprising:
- a power management module coupleable to a set of memory devices and to a set of spare power modules, the power management module configured to:
- determine a first amount of power being consumed by the set of memory devices, the first amount of power provided by a set of power modules, and
- in response to a first predetermined event, modify a second amount of power provided to the set of memory devices via the set of spare power modules.
