Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the clock frequency is increased to improve communication speed, then the data transmission speed between host device and memory apparatus is improved, but the pulse width of the strobe signal becomes too short providing insufficient time margin for data storage
Solution Approach 1:
The strobe signal generation device segments the original strobe signal into multiple divided strobe signals (first through fourth data strobe signals). Each divided signal has an extended pulse width that provides sufficient time margin for data storage operations, even when the original strobe signal pulse width is too short due to high clock frequency operation.
Solution Approach 2:
The patent introduces a new temporal dimension by generating multiple strobe signals with different timing and extended durations. Instead of relying on a single narrow strobe signal pulse, the system creates a sequence of divided strobe signals that collectively cover the required time window for data storage, effectively extending the functional duration beyond the original pulse width limitation.
2Reliability
If the strobe signal pulse width is extended to provide sufficient time margin for data storage, then the reliability of high-speed memory operations is improved, but the communication speed with host device must be reduced
Solution Approach 1:
The device segments the high-speed data transmission into multiple phases, each handled by a divided strobe signal with extended pulse width. This segmentation allows the memory apparatus to reliably capture data at each phase while maintaining overall high communication throughput, as the division enables parallel or sequential processing of data chunks.
Solution Approach 2:
The enable signal generating section generates division enable signals in advance based on the original strobe signal, preparing the timing framework for subsequent data storage operations. This preliminary action ensures that the divided strobe signals are properly synchronized and timed before actual data capture, maintaining communication speed while ensuring reliability.
3Duration of action of moving object
If multiple divided strobe signals are generated to extend pulse width, then the time margin for data storage is improved, but the device complexity increases
Solution Approach 1:
The patent merges the functions of strobe signal generation, division, and enabling into a single integrated strobe signal generation device. By combining these functions, the device achieves extended effective strobe duration through multiple divided signals while minimizing the increase in overall device complexity compared to using separate components for each function.
Solution Approach 2:
The strobe signal generation device performs multiple functions: generating the original strobe signal, creating division enable signals, producing delayed strobe signals, and generating multiple divided strobe signals. This multi-functionality reduces the need for separate dedicated components for each operation, thereby limiting the increase in device complexity while achieving extended pulse width coverage.
