1Speed
If semiconductor devices operate at faster speeds, then processing capability is improved, but power consumption increases and signal transmission accuracy deteriorates
Solution Approach 1:
The patent implements dynamic adjustment of driving force levels based on signal transmission quality feedback. The system transitions from static driving force settings to dynamic control where the first semiconductor device adjusts its driving force in response to restoration signal quality, enabling optimal power consumption at different operating speeds
Solution Approach 2:
The patent establishes a feedback loop where the second semiconductor device generates restoration signals that are transmitted back to the first semiconductor device. The first device compares these restoration signals with original signals and uses the comparison results to adjust future driving force levels, creating a closed-loop control system that optimizes power consumption based on actual transmission performance
2Speed
If semiconductor devices operate at faster speeds, then processing capability is improved, but signal transmission accuracy deteriorates
Solution Approach 1:
The feedback mechanism compares restoration signals with original signals to detect transmission degradation. When accuracy deteriorates at higher speeds, the system receives feedback indicating poor signal quality and responds by adjusting driving force levels to restore transmission accuracy
Solution Approach 2:
The patent changes the driving force parameter dynamically based on operating conditions. By adjusting this critical parameter in response to speed changes and signal quality feedback, the system maintains transmission accuracy across different operating speeds
3Measurement precision
If driving force is increased to improve signal transmission, then transmission accuracy is improved, but power consumption increases
Solution Approach 1:
The system transitions from fixed driving force levels to dynamic adjustment based on actual transmission needs. The first semiconductor device changes driving force levels in response to feedback from signal comparisons, applying maximum driving force only when necessary and reducing it when transmission quality is sufficient
Solution Approach 2:
The patent implements parameter changes in driving force levels to optimize the balance between transmission accuracy and power consumption. By dynamically adjusting this parameter based on feedback, the system achieves accurate transmission at minimal power consumption

AI summary
A semiconductor system may include a first semiconductor device and a second semiconductor device. The first semiconductor device compares a received signal with an original signal to generate a driving force control signal. The first semiconductor device also drives the original signal using a driving force in accordance with the driving force control signal to output an external transmission signal. The second semiconductor device receives the external transmission signal to generate a positive signal and a negative signal. The second semiconductor device also generates a restoration signal in response to the positive signal and the negative signal. The second semiconductor device additionally outputs the restoration signal as the external transmission signal to the first semiconductor device.
