Engineering Contradiction Analysis
1Measurement precision
If voltage amplification is performed in the data transmission circuit during read operations, then signal detection capability is improved, but current consumption increases
Solution Approach 1:
The patent changes the operating parameters of the amplification circuit by detecting the actual voltage level difference on the second data lines and dynamically adjusting the amplification factor. When the voltage difference is already sufficient, the amplification is reduced or disabled, thereby lowering current consumption while maintaining adequate signal detection capability.
Solution Approach 2:
The patent implements a feedback mechanism where the voltage level difference on the second data lines is continuously monitored and fed back to control the amplification process. This feedback allows the circuit to adjust its operation in real-time, preventing excessive amplification and the associated high current consumption while ensuring reliable signal detection.
2Reliability
If voltage amplification is performed to ensure signal integrity on long data lines, then signal quality is improved, but voltage levels may exceed preset thresholds causing distortion
Solution Approach 1:
The patent uses feedback control where the amplified voltage level is monitored and compared against preset thresholds. When the voltage level approaches or exceeds the threshold, the amplification is automatically reduced or stopped, preventing voltage distortion while maintaining signal integrity through controlled amplification.
Solution Approach 2:
The patent applies preliminary anti-action by setting up voltage threshold limits and control mechanisms before excessive amplification can occur. The circuit is designed with predetermined voltage level constraints that prevent the amplification process from generating harmful voltage distortion in the first place.
3Length of moving object
If the data transmission circuit is positioned adjacent to the data storage area, then data line length is reduced, but loading on short data lines becomes insufficient for proper signal transmission
Solution Approach 1:
The patent applies local quality by implementing different transmission strategies for different data line segments. For short data lines with low loading, the circuit provides enhanced local amplification or signal conditioning to ensure adequate signal quality, while longer lines receive standard amplification, optimizing performance for each local condition.

AI summary
A data transmission circuit includes a read data transmission unit configured to, when a read signal is asserted, detect and amplify a voltage level of a first data line, transmit an amplified voltage level to a second data line, and substantially prevent a voltage level of the second data line from being amplified to be substantially equal to or more than a preset voltage level, and a write data transmission unit configured to transmit the voltage level of the second data line to the first data line when a write signal is asserted.
