Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a fixed programming order is used for memory dies in a metablock, then the storage device structure is simple and easy to manufacture, but performance bottlenecks occur when slower memory dies are present
Solution Approach 1:
The patent implements dynamic programming order adjustment by allowing the storage device to change the programming sequence of memory dies based on their actual performance characteristics. Instead of a static fixed order, the system dynamically reorders memory die programming to prioritize faster dies, thereby resolving the contradiction between maintaining simple structure and achieving high performance.
2Productivity
If memory dies are programmed in parallel to optimize performance, then throughput increases, but slower memory dies create bottlenecks that reduce overall efficiency
Solution Approach 1:
The patent applies local quality by treating each memory die individually based on its performance characteristics. Instead of uniformly programming all memory dies in the same sequence, the system assigns different programming priorities to different memory dies according to their specific speed characteristics, thereby optimizing overall throughput while minimizing wait times caused by slower dies.
3Productivity
If the programming order is altered to prioritize faster memory dies, then performance improves, but additional control logic is required
Solution Approach 1:
The patent changes the parameter of programming order based on performance parameters of individual memory dies. The system monitors and identifies the relative speeds of different memory dies and adjusts the programming sequence accordingly, transforming a static control approach into a parameter-driven dynamic control approach that optimizes programming speed without requiring fundamentally new control architecture.

AI summary
A programming order of memory dies of a metablock is typically fixed. However, in some storage architectures, this may cause performance bottlenecks. As such, the programming order of the memory dies may be altered to reduce or eliminate performance bottlenecks.
