Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a memory device performs training operation without dedicated training data management structures, then device complexity is reduced, but training data availability and utilization efficiency deteriorate
Solution Approach 1:
The memory device is segmented into distinct functional components: a training operation controller dedicated to training operations, a normal operation controller for standard operations, and a training buffer specifically for storing training data. This segmentation allows each component to be optimized for its specific function, improving training data management without significantly increasing overall device complexity.
Solution Approach 2:
A training buffer is introduced as an intermediary storage structure between the training operation controller and the memory cell array. This intermediary component enables efficient training data management by providing a dedicated space for storing and managing training data, thereby improving training data availability without requiring major changes to the overall device architecture.
2Quantity of substance
If training data is stored in general buffer during training operation, then buffer capacity is sufficient, but training data utilization efficiency during normal operation deteriorates
Solution Approach 1:
The training buffer is designed with local quality optimized for training data storage and management. It has specific characteristics tailored for training operations, such as appropriate size, access speed, and management mechanisms. This local optimization ensures that the training buffer can efficiently store and provide training data during both training and normal operations, thereby improving training data utilization efficiency while maintaining sufficient capacity.
3Device complexity
If memory device uses unified controller for both training and normal operations, then controller structure is simplified, but operational performance during normal operation deteriorates
Solution Approach 1:
The controller is segmented into a training operation controller and a normal operation controller. The training operation controller is specifically designed and optimized for managing training operations, including training data management and training process control. This segmentation allows each controller to be optimized for its specific operational mode, thereby improving operational performance and reliability without significantly increasing overall controller structure complexity.
