Memory Module Testing Through Processed Signal Logging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing system analysis approaches using logic analyzers fail to capture the complete operation sequence of memory due to storage limitations and signal distortion, necessitating repeated testing.
Innovation Solution
A test system comprising a data collector and a test monitor that processes signals between a controller and memory to generate processed signals, which are then encoded into log information to determine the operation status of the system platform.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a logic analyzer is used to analyze memory operation sequence, then system analysis capability is provided, but storage space limitation prevents obtaining whole operation sequence
Solution Approach 1:
The patent extracts only the necessary timing and operation sequence information from the complex signal data, storing only critical timing parameters (tRAS, tRC, tRP, tRCD) and operation sequences rather than complete raw signals, thereby reducing storage requirements while preserving essential memory operation analysis capability
Solution Approach 2:
The patent segments the memory operation analysis into discrete timing parameters and operation sequences, breaking down the continuous signal stream into measurable timing intervals and standardized operation codes, enabling efficient storage and analysis of memory behavior without requiring complete signal capture
2Speed
If processing speed of memory increases, then performance is improved, but signal distortion occurs in transmission line
Solution Approach 1:
The patent introduces an intermediary measurement approach that captures timing parameters and operation sequences rather than directly transmitting high-speed signals through vulnerable transmission lines. By measuring and recording timing intervals (tRAS, tRC, tRP, tRCD) and operation codes, the system preserves signal integrity information without requiring high-fidelity signal transmission
Solution Approach 2:
The patent creates a digital copy of the memory operation characteristics by recording timing parameters and operation sequences, replacing the need to physically transmit and analyze the original high-speed signals. This copied representation maintains all necessary diagnostic information while avoiding signal distortion issues
3Measurement precision
If signal distortion occurs, then error detection becomes difficult, but repeated testing is required
Solution Approach 1:
The patent performs preliminary measurement and recording of timing parameters and operation sequences during normal memory operation, capturing diagnostic information before signal distortion can occur or before testing needs to be repeated. This preliminary data collection enables subsequent error analysis without requiring re-testing
