Sequenced Memory Component Activation for Peak Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing memory system activation methods consume high peak power, generate excessive heat, and occupy significant space, as they activate all memory components simultaneously, which is inefficient and costly, especially in mobile devices.
Innovation Solution
Implementing a sequenced activation of memory components, where some but not all memory components are activated at the same time, using a designated activation sequence to reduce peak power consumption and allow for smaller voltage regulators, thereby enhancing efficiency and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If all memory components are activated simultaneously, then the memory system becomes operational quickly, but peak power consumption increases and heat generation becomes excessive
Solution Approach 1:
The patent divides the memory components into multiple groups or banks that are activated in sequential stages rather than all at once. This segmentation allows the system to spread out the power consumption over time, reducing peak power requirements while still achieving relatively fast overall activation by parallel activating multiple groups in succession
2Productivity
If all memory components are activated simultaneously, then the memory system is fully operational, but heat generation becomes excessive and space requirements increase
Solution Approach 1:
The memory system is divided into multiple activatable groups, allowing the system to achieve full operational capacity through sequential activation rather than simultaneous activation. This segmentation reduces heat generation by spreading the thermal load over time and allows for better thermal management in the device
3Productivity
If all memory components are activated simultaneously, then the system is ready for use, but voltage regulators must be large and costly
Solution Approach 1:
By segmenting the memory activation into multiple groups, the patent reduces the peak current demand that voltage regulators must handle. This allows for the use of smaller, less expensive voltage regulators that can be activated in sequence rather than requiring large regulators capable of handling the sum of all memory component activation currents simultaneously
Solution Approach 2:
The system employs periodic or staged activation of memory groups, where each group is activated in successive time periods. This periodic action allows voltage regulators to operate at lower power levels during each stage, reducing the size and cost requirements compared to simultaneous activation of all components

AI summary
A method includes providing, in accordance with a memory component activation sequence, a first activation power to a first memory component of a plurality of memory components for a first time period, where the first activation power is provided in the absence of providing an activation power to at least one other memory component of the plurality of memory components during the first time period. The method includes providing, in accordance with the memory component activation sequence, a second activation power to a second memory component for a second time period.
