Engineering Contradiction Analysis
1Speed
If data transmission rate is advanced, then transmission speed is improved, but data errors occur more frequently
Solution Approach 1:
The patent implements dynamic adjustment of scrambling enablement based on real-time error detection. The system transitions from a static scrambling configuration to a dynamic one where the scrambling function is enabled or disabled according to the current transmission conditions and error rates, allowing the system to adapt to varying transmission quality at different data rates
Solution Approach 2:
The patent employs continuous monitoring of data transmission quality through error detection mechanisms. The system uses feedback from error detection results to adjust the scrambling function's operational state, creating a closed-loop control system that responds to transmission conditions and adjusts scrambling enablement accordingly to maintain reliability at high data rates
2Reliability
If data scrambling technique is enabled, then data error protection is improved, but transmission efficiency deteriorates
Solution Approach 1:
The patent makes the scrambling function dynamically adjustable rather than fixed. The system can enable scrambling when error conditions are detected and disable it when transmission conditions are good, optimizing the balance between error protection and transmission efficiency based on real-time system state
Solution Approach 2:
The patent changes the operational parameter of the scrambling function from a fixed enabled state to a dynamically adjustable state. By modifying the enablement parameter based on transmission quality metrics, the system optimizes the trade-off between error protection overhead and transmission efficiency under different operating conditions

AI summary
The invention introduces a method for reducing data errors in transceiving of a flash storage interface, performed by a processing unit of a first side, at least including: descrambling first data from a second side via an enabled descrambler of a lowest layer; determining whether a reception error is occurred by continuously monitoring first descrambled data; and when the reception error is occurred, disabling the descrambler of the lowest layer and issuing a first request to the second side for directing the second side to disable a scrambler, thereby disabling the second side to protect second data to be transmitted to the first side by using a data scrambling technique.
