Engineering Contradiction Analysis
1Speed
If multiple registers are used to shift commands in high-speed semiconductor systems, then data transmission rates can be maintained, but device complexity and the number of components increase
Solution Approach 1:
The patent combines multiple register functions into a single phase-shifting circuit that can simultaneously handle multiple command signals. The phase-shifting circuit uses a unified structure with clock signals of different phases to achieve command shifting without requiring separate registers for each operation, thereby reducing overall device complexity while maintaining high-speed data transmission.
Solution Approach 2:
The phase-shifting circuit is designed as a universal component that can shift multiple different command signals (such as READ, WRITE, and other control commands) using the same circuit structure. This multi-functional approach eliminates the need for dedicated registers for each command type, reducing the total number of components while preserving high-speed operation capabilities across all command types.
2Productivity
If command phase shifting is implemented using traditional methods, then operational efficiency is maintained, but the number of components and circuit complexity increase
Solution Approach 1:
The patent implements preliminary phase shifting of clock signals before they reach the command latching stage. By pre-generating clock signals with different phases and using them to latch commands at appropriate times, the system achieves efficient command phase shifting without requiring complex post-processing circuits. This preliminary action approach maintains operational efficiency while simplifying the overall circuit architecture.
3Speed
If high-speed operation is pursued, then data transmission rates improve, but latency-induced phase shifts of commands become more significant
Solution Approach 1:
The patent applies preliminary anti-action by compensating for latency-induced phase shifts before they affect command execution. The system uses pre-calibrated phase-shifting circuits that anticipate and counteract the time delays inherent in high-speed operations. By pre-adjusting the phase of clock signals based on expected latency, the system maintains accurate command timing despite high-speed operation, effectively neutralizing the negative effects of latency.
