Flash Storage Interface De-Emphasis Tuning for Fewer Data Errors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flash memory devices experience increased data errors due to high data transmission rates in flash storage interfaces, necessitating methods to reduce errors in data transmission.
Innovation Solution
A processing unit continuously monitors data and control frames for errors and triggers a de-emphasis adjustment in the PHY layer when errors are detected, adjusting the de-emphasis setting to minimize intersymbol interference and improve signal-to-noise ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data transmission rate is increased in flash storage interface, then productivity is improved, but data errors increase
Solution Approach 1:
The patent implements a feedback mechanism where the receiving end detects data errors and sends error information back to the transmitting end. The transmitting end then adjusts its de-emphasis setting based on this feedback, creating a closed-loop control system that dynamically optimizes transmission quality while maintaining high data rates.
Solution Approach 2:
The patent changes the de-emphasis parameter dynamically based on detected error conditions. By adjusting the de-emphasis setting (a physical parameter of the transmission signal), the system adapts to varying transmission conditions, reducing intersymbol interference and minimizing data errors at high transmission rates.
2Reliability
If de-emphasis adjustment is made to reduce data errors, then reliability is improved, but device complexity increases
Solution Approach 1:
The system performs self-adjustment through automatic error detection and feedback-based parameter modification. The transmitting end autonomously modifies its de-emphasis setting based on error feedback from the receiving end, eliminating the need for external intervention or complex manual control mechanisms.
Solution Approach 2:
The de-emphasis setting is made dynamic rather than static, allowing it to change based on real-time transmission conditions. This dynamic adjustment capability enables the system to adapt to varying signal quality without requiring overly complex control architecture.

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, comprising: continuously monitoring data frames and/or control frames from a second side; and triggering a de-emphasis adjustment when information of the data frame and/or the control frame indicates that the lowest layer of the second side detects errors from received data.
