Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional memory structure with signal reflectors is used, then memory operation can be maintained, but reflected signals cannot be effectively reduced, causing system instability
Solution Approach 1:
The patent converts the harmful reflected signals into beneficial absorbed energy by introducing absorption units (resistors) at specific locations in the circuit. These absorption units dissipate the reflected signal energy, transforming the harmful reflection into harmless heat energy, thereby improving memory operation stability.
Solution Approach 2:
The patent introduces an intermediary absorption unit (resistor) between the memory and the signal source/other components. This intermediary component intercepts and absorbs the reflected signals before they can cause interference, acting as a mediator that protects the memory system from harmful reflections.
2Quantity of substance
If multiple memories are integrated to increase capacity, then memory capacity is improved, but circuit layout complexity and number of layers substantially increase
Solution Approach 1:
The patent merges multiple memory devices into a single integrated memory structure with shared address and control lines. By combining multiple memories and using common signal paths where possible, the patent reduces the overall circuit layout complexity while maintaining increased memory capacity.
Solution Approach 2:
The patent arranges multiple memories in a multi-dimensional layout configuration, organizing them in rows and columns with systematic address line assignments. This dimensional organization allows efficient routing of address and control signals across multiple memories without substantially increasing the number of layers or routing complexity.

AI summary
A memory structure with reduced-reflection signals at least includes a processing unit; a lumped circuit unit, connected to the processing unit; a plurality of memories, connected to the lumped circuit unit; and a reflected signal absorption unit, disposed at one end of the lumped circuit unit. Thereby, with the cooperation of the processing unit with each memory for signal transmission, the reflected signal absorption unit can be used to absorb the reflected signals so as to reduce the number of reflected signals during signal transmission, achieving the effect of stable operation for the memories.
