Dynamic Non-Volatile Memory Allocation for Computing Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current computing systems lack the ability to dynamically share non-volatile memory across volatile main memory and persistent storage memory, failing to adapt to dynamic changes in read and write operations performed by applications.
Innovation Solution
A computing system with a first memory, a second memory of a different type, and a third configurable non-volatile memory that dynamically adjusts its resources to function with either the first or second memory based on application needs, reallocating resources between volatile main memory and solid state storage memory as necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If non-volatile memory is statically allocated to either volatile main memory or persistent storage memory, then the system structure is simple and stable, but the memory resources cannot adapt to dynamic changes in application read and write loads
Solution Approach 1:
The patent implements dynamic memory allocation by enabling the non-volatile memory to automatically switch between functioning as volatile main memory and persistent storage memory based on real-time monitoring of application read and write operation loads, replacing static allocation with adaptive dynamic reconfiguration
Solution Approach 2:
The system performs self-adjustment through automatic monitoring and reconfiguration of non-volatile memory functionality without requiring manual intervention or complex external memory management, allowing the memory subsystem to serve itself by adapting to workload changes
2Productivity
If non-volatile memory resources are dynamically reconfigured based on application needs, then memory efficiency and adaptability improve, but the control and monitoring mechanisms become more complex
Solution Approach 1:
The patent implements feedback mechanisms by monitoring the loads on volatile main memory and persistent storage memory, using this information to determine when and how to reconfigure non-volatile memory resources, creating a closed-loop control system that continuously optimizes memory allocation based on actual usage patterns
3Quantity of substance
If the non-volatile memory functions exclusively with one memory type, then the system is simpler to manage, but the memory resources are wasted when the allocated memory type is not sufficient
Solution Approach 1:
The patent enables the non-volatile memory to perform multiple functions by allowing it to dynamically switch between augmenting volatile main memory and supporting persistent storage memory, making a single memory resource universally applicable to different memory subsystems based on real-time needs

AI summary
In the embodiment a determination is made, for one or more applications being executed by the computing system, of an amount of the first or second memory being used by the one or more applications. Based on the determination, a portion of the memory resources of the third memory are configured to function with the first or second memory when it is determined that the amount of the first or second memory being used by the one or more applications is not sufficient for the memory needs of the one or more applications and a portion of the memory resources of the third memory are removed from functioning with the first or second memory when it is determined that the amount of the first or second memory being used by the one or more applications is more than is needed for the memory needs of the one or more applications.
