Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current memory systems lack the ability to differentiate between various combinations of errors detected by both the memory system and the host system, leading to potential introduction of additional errors and reduced reliability in data transfers.
Innovation Solution
Incorporating syndrome check circuitry that includes additional circuitry such as logic gates and inverters to compare signals from the memory system and the host system, allowing for the differentiation of different error states and improving diagnostic capabilities.

1Measurement precision
If syndrome check circuitry is added to differentiate between error types, then error diagnostic capability is improved, but device complexity increases
Solution Approach 1:
The syndrome check circuitry is segmented into distinct functional blocks: a first syndrome check circuit for detecting errors in data from the memory device, a second syndrome check circuit for detecting errors in data from the host device, and a comparison circuit for analyzing the relationship between the two error detection results. This segmentation allows each block to perform a specific function, improving diagnostic capability while keeping the overall complexity manageable through modular design.
2Reliability
If additional circuitry is added to compare signals from memory system and host system, then reliability of data transfers is improved, but device complexity increases
Solution Approach 1:
The patent introduces an intermediary comparison circuit that acts as a mediator between the first syndrome check circuit (monitoring memory device errors) and the second syndrome check circuit (monitoring host device errors). This intermediary component analyzes the relationship between the two error detection results to determine whether errors are correlated, providing enhanced reliability assessment without requiring direct complex interaction between the two main systems.

AI summary
Methods, systems, and devices for syndrome check functionality to differentiate between error types are described. A host system, a memory system, or some combination of both may include syndrome check circuitry to provide enhanced error diagnostic capabilities for data communicated between the host system and the memory system. The syndrome check circuitry may receive a first signal from the memory system indicating whether the memory system detected and attempted to correct an error in the data and may receive a second signal from the host system indicating whether the host system detected an error in the received data. The syndrome check circuitry may compare the first signal and the second signal using a set of logic gates to differentiate between different combinations of errors detected at one or both of the memory system or the host system.
