Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If preset operating parameters are used for memory interface access, then device operation is simple and stable, but sampling quality of data transmitted between memory interface and non-volatile memory module deteriorates under changing system conditions
Solution Approach 1:
The patent implements dynamic parameter adjustment by enabling the memory control circuit unit to automatically update interface parameters (such as delay amounts and sampling clock phases) based on real-time system status detection. This transforms the static preset parameter approach into a dynamic adaptive system that responds to changing operating conditions, thereby maintaining high sampling quality without requiring manual intervention.
Solution Approach 2:
The patent establishes a feedback mechanism where the memory control circuit unit continuously detects system status (including temperature, voltage, and operating frequency) and uses this information to determine whether parameter updates are needed. The feedback loop compares current system conditions against stored reference conditions and triggers parameter updates when deviations exceed thresholds, ensuring optimal sampling quality through closed-loop control.
2Reliability
If interface parameters are dynamically updated based on system status, then sampling quality is maintained or improved, but device complexity and control complexity increase
Solution Approach 1:
The patent implements self-service functionality where the memory control circuit unit autonomously performs system status detection, parameter comparison, and parameter updates without requiring external intervention. The circuit monitors its own operating conditions and automatically adjusts interface parameters when needed, reducing the need for complex external control systems while maintaining high data transmission quality.
Solution Approach 2:
The patent employs preliminary action by pre-storing reference system status data and corresponding optimal interface parameters in the memory control circuit unit during manufacturing or initialization. When the system operates, it compares current status against these pre-stored references and retrieves appropriate parameters in advance, eliminating the need for complex real-time calculations and reducing control complexity.
3Productivity
If preset parameters are used for memory access, then device operation is simple, but data transmission efficiency deteriorates under varying system conditions
Solution Approach 1:
The patent uses feedback mechanisms to automatically detect system status changes and trigger parameter updates, eliminating the need for manual parameter adjustment. The memory control circuit unit continuously monitors operating conditions and automatically retrieves optimized parameters from stored references, maintaining high data transmission efficiency across varying system conditions while keeping the operation process simple and automated.
Solution Approach 2:
The patent implements parameter changes by automatically adjusting interface parameters (such as delay amounts, sampling clock phases, and signal timing) based on detected system status. This dynamic parameter adaptation allows the system to optimize data transmission efficiency for different operating conditions without requiring manual intervention, effectively resolving the contradiction between operational simplicity and transmission efficiency.
