Solution Overview

Problem

Existing memory sub-systems face challenges in efficiently retrieving and analyzing signal, log, and state information, especially when failures or fault conditions render the system inoperable, leading to costly and time-consuming diagnostic processes.

Innovation Solution

Incorporating special purpose circuitry, such as the signal analyzer component, within the memory sub-system to monitor, analyze, and persistently store signal, log, and state information, allowing for expanded data storage and retrieval without the need for physical removal or specialized equipment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional memory sub-system diagnostic methods are used, then physical removal and specialized equipment are required, but this leads to costly and time-consuming diagnostic processes

Engineering Contradiction:
Improvesignal information analysis capabilityVSAvoiddiagnostic process time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent implements preliminary action by continuously monitoring and storing signal, log, and state information in persistent storage before failures occur. The signal analyzer component captures waveform data, digital logic signals, and operational states during normal operation, so when a failure occurs, the diagnostic data is already available without requiring physical removal or specialized equipment for capture.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary component - the signal analyzer with persistent storage - that mediates between the memory sub-system and diagnostic processes. This intermediary continuously records operational data and stores it locally, eliminating the need for external specialized equipment and reducing diagnostic time while maintaining high measurement precision.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If traditional diagnostic approaches are used, then physical removal of components is required, but this increases device complexity and manufacturing costs

Engineering Contradiction:
Improvediagnostic capabilityVSAvoidsub-system structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the signal analysis functionality and persistent storage capability directly into the memory sub-system architecture. The signal analyzer component is integrated with the memory controller and persistent storage is incorporated into the sub-system, combining multiple diagnostic functions into a unified structure that improves reliability without proportionally increasing overall device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The memory sub-system performs self-diagnostic monitoring through the integrated signal analyzer that continuously captures and stores operational data. The system serves its own diagnostic needs by maintaining local records of signal waveforms, logic states, and operational parameters, eliminating the need for external physical removal and specialized testing equipment.

Inventive Principle:
Principle #25Self-service

3Loss of information

If comprehensive signal monitoring is implemented, then detailed diagnostic data is captured, but this increases data storage requirements and processing overhead

Engineering Contradiction:
Improvesignal information retentionVSAvoiddata storage volume
Core Design Contradiction:
Loss of informationVSQuantity of substance

Solution Approach 1:

The patent applies local quality by having the signal analyzer monitor and store different types of information (analog waveforms, digital logic signals, operational states) with appropriate detail levels tailored to their specific diagnostic value. Critical signal transitions and error states are captured with high fidelity while routine operational data is recorded at lower resolution, optimizing storage efficiency while maintaining comprehensive diagnostic capability.

Inventive Principle:
Principle #3Local quality

AI summary

A plurality of signals within a memory sub-system are analyzed by a signal analyzer component. Relevant signals among the plurality of signals are determined by the signal analyzer component such that the relevant signals comprise a subset of signals among the plurality of signals. Information corresponding to the relevant signals is sampled by the signal analyzer component and the signal analyzer component is responsible for extracting the information corresponding to the relevant signals among the plurality of signals.
