Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple memory packages are activated simultaneously to increase data throughput, then data input/output speed is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic control of memory package activation through a control circuit that selectively activates or deactivates specific memory groups based on system requirements. This allows the memory module to adapt its power consumption and performance characteristics in real-time, activating only the necessary number of memory packages rather than keeping all packages continuously active.
Solution Approach 2:
The memory module is divided into multiple independent memory groups, each containing one or more memory packages. This segmentation allows selective activation of individual memory groups through a multiplexer circuit and control logic, enabling the system to activate only the required number of memory groups based on data throughput requirements, thereby reducing overall power consumption while maintaining necessary performance.
2Productivity
If all memory packages are continuously activated to maintain high data throughput, then data input/output speed is maintained, but power consumption increases
Solution Approach 1:
The control circuit periodically evaluates system requirements and dynamically adjusts the activation state of memory groups accordingly. Rather than maintaining continuous activation of all memory packages, the system performs periodic assessments and activates or deactivates memory groups as needed, reducing power consumption during periods of lower demand while maintaining high throughput capability when required.
Solution Approach 2:
The system changes operational parameters by selectively modifying the activation state of different memory groups based on address signals and system requirements. This parameter change approach allows the memory module to transition between different power consumption states and performance levels, optimizing the balance between data throughput and power usage.
3Reliability
If more memory groups are activated to handle increased data load, then data input/output reliability is improved, but loading increases
Solution Approach 1:
By segmenting the memory module into multiple independent memory groups with dedicated input/output pins and control logic, the system can selectively activate only the necessary number of groups to handle the current data load. This segmentation reduces the loading on each individual active group while maintaining overall reliability through redundant pathways and selective activation.
Solution Approach 2:
The multiplexer circuit and control logic act as intermediaries that manage the activation and deactivation of memory groups based on system requirements. This intermediary control mechanism optimizes the balance between reliability and loading by activating sufficient memory groups to handle the data load while minimizing the number of active groups to reduce overall loading and complexity.
