Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional memory initialization is performed with standard clock signals, then the process is simple and fast, but sampling point calculation errors occur leading to memory usage errors
Solution Approach 1:
The patent applies preliminary action by performing sampling point detection and calibration before actual memory operations. The host control module executes tuning commands and analyzes setting data in advance to determine accurate sampling points, ensuring reliable memory recognition from the start of operations.
Solution Approach 2:
The patent implements dynamics by making the clock signal adjustable and modifiable. The host control module can modify clock signal parameters (frequency, phase, waveform) dynamically during initialization based on detected sampling point requirements, allowing adaptation to different memory devices and conditions.
2Measurement precision
If the clock signal is modified to improve sampling point detection accuracy, then measurement precision improves, but the initialization process becomes more complex
Solution Approach 1:
The patent applies parameter changes by modifying clock signal characteristics (frequency, phase, waveform shape) to optimize sampling point detection. The host control module adjusts these parameters systematically while analyzing the resulting setting data to identify the optimal sampling point configuration.
Solution Approach 2:
The patent implements feedback by using the setting data returned from the memory device to refine sampling point determination. The host control module analyzes the feedback information and adjusts clock signal parameters iteratively until accurate sampling points are identified.
3Adaptability or versatility
If multiple tuning commands are transmitted to detect sampling points under different conditions, then adaptability improves, but the initialization time increases
Solution Approach 1:
The patent applies periodic action by transmitting tuning commands at different clock frequencies and phases in a systematic sequence. This periodic variation allows the system to identify sampling points that remain stable across different conditions, enhancing adaptability without requiring excessive testing.

AI summary
An electronic device and method in which a tuning process is performed during memory initialization, so as to reduce the occurrence of data read errors. The device may include a clock generator that generates a clock signal transmitted to a memory device, and a host control module that transmits to the memory device a change signal changing at least a portion of the clock signal, and/or a tuning related command. The host control module may receive setting data from the memory device, corresponding to at least one of the change signal and the tuning related command.
