Coordinated Syndrome Matching for Memory Data Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing memory systems struggle to reliably detect and correct errors, particularly when multiple bit errors occur, leading to potential data integrity issues during data transfers between memory devices and host systems.
Innovation Solution
Implement coordinated syndrome matching procedures at both the memory device and host device to enhance error detection capabilities, allowing for the validation or discard of data based on combined results from both systems, thereby increasing data transfer reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If coordinated syndrome matching procedures are implemented at both memory device and host device, then error detection capability is improved, but device complexity increases
Solution Approach 1:
The error detection function is segmented into two independent syndrome matching procedures: one executed at the memory device and another at the host device. Each procedure independently processes error detection for its respective data portion, allowing distributed error detection capability while maintaining modular system architecture that manages complexity.
Solution Approach 2:
The memory device performs syndrome matching on the first portion of data before transmitting it to the host device. This preliminary error detection action allows early identification of errors in the first data portion, reducing the need for extensive host-side error handling and improving overall system reliability.
2Reliability
If syndrome matching is performed at both memory device and host device, then data transfer reliability is improved, but processing time increases
Solution Approach 1:
Syndrome matching operations are performed periodically at both memory device and host device during data transfer operations. This periodic execution allows error detection to be integrated into the normal data transfer rhythm without requiring continuous additional processing, thereby limiting time overhead while maintaining high reliability.
Data Source
AI summary
Methods, systems, and devices for coordinated error protection are described. A set of data and an indication of whether a first management procedure performed by a memory device on the set of data detected one or more errors in the set of data may be received at a host device. At the host device, a second error management procedure may be performed on the set of data received from the memory device. Based on the received indication and the second error management procedure, multiple bits indicating whether one or more errors associated with the set of data were detected at the memory device, the host device, or both may be generated. The set of data may be validated or discarded based on the multiple bits.
