Memory Storage Device Host Memory Buffering Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The operating stability of memory storage devices is compromised due to repeated startup operations of host memory buffering in unstable environments.
Innovation Solution
A memory management method and system that establish a connection between the memory storage device and the host system, detect the status of the memory storage device within a specified time range, and determine whether to use host system memory or enter a low power consumption mode based on the detected status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the memory storage device repeatedly executes startup operation of host memory buffering to access host system memory, then the memory storage device can utilize host system memory as buffer, but the operating stability of the memory storage device decreases
Solution Approach 1:
The patent applies preliminary action by detecting the operating environment status before enabling host memory buffering. The controller checks whether the host system and memory storage device are in a stable state before allowing the memory storage device to access the host system's memory as buffer, thereby preventing repeated startup operations that would compromise operating stability.
2Productivity
If the memory storage device accesses host system memory for buffer operations, then memory resources are optimized, but the complexity of environment detection and stability judgment increases
Solution Approach 1:
The patent implements feedback by continuously monitoring the operating environment status and the stability of host memory buffering operations. Based on the detection results, the controller dynamically adjusts whether to enable or disable host memory buffering, creating a closed-loop control system that optimizes memory utilization while maintaining operational simplicity.
