Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the memory system uses a conventional command processing approach without acquiring setting information, then the system structure remains simple, but the performance and efficiency are reduced
Solution Approach 1:
The controller acquires setting information from the memory device before executing command operations. This preliminary action includes obtaining configuration information, organization information, and addressing information, which enables the controller to optimize subsequent data processing operations and improve overall productivity without permanently increasing system complexity
Solution Approach 2:
The memory device provides feedback to the controller through acknowledgement signals that contain setting information. This feedback mechanism allows the controller to adapt its command operations based on the actual characteristics of the memory device, thereby improving data processing efficiency while maintaining a relatively simple system architecture
2Reliability
If the controller acquires and checks setting information before command operations, then the efficiency and stability of data processing is improved, but the complexity of the controller increases
Solution Approach 1:
The controller performs preliminary checks of setting information including configuration information, organization information, and addressing information before executing command operations. This preliminary verification ensures stable and reliable data processing by preventing invalid operations, while the checks are designed to be efficient and not overly complex
Solution Approach 2:
The controller receives feedback in the form of acknowledgement signals from the memory device that contain setting information. By utilizing this feedback, the controller can make informed decisions about command operations, improving reliability without requiring complex internal logic, as the decision-making information is provided externally by the memory device
