Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the memory chip is enabled in a low-temperature environment, then the memory chip can operate, but the writing time is longer and the writing stability is not high
Solution Approach 1:
The temperature detection module performs temperature detection before the memory chip is enabled. The control chip receives the detection result and determines whether to enable the memory chip based on the temperature. This preliminary temperature check prevents low-temperature operation that would cause long writing time and poor stability, allowing the system to take preparatory actions (heating or disabling) before the main operation begins.
2Reliability
If a temperature detection module is added to detect temperature and prevent low-temperature operation, then writing stability is improved, but the device complexity increases
Solution Approach 1:
The temperature detection module uses a diode as the temperature sensitive unit, which is a common semiconductor component that can serve multiple functions. The same diode structure that is typical in memory circuits is utilized for temperature detection, allowing the detection function to be integrated without adding entirely new component types. The control chip also performs dual functions of temperature monitoring and operation control, reducing the need for separate dedicated control hardware.
3Measurement precision
If the temperature detection unit is calibrated by adjusting the resistance value of the adjustable resistor unit, then the detection accuracy is improved, but the device complexity increases
Solution Approach 1:
The adjustable resistor unit allows dynamic adjustment of resistance values to calibrate the temperature detection unit. Instead of using fixed resistance values that would require multiple discrete resistor components for different calibration points, the adjustable resistor provides continuous or stepped adjustment capability through a single integrated component, reducing overall circuit complexity while improving measurement precision.
