Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing density and number of memory cells in semiconductor storage apparatuses lead to increased power consumption in the data transmission path, posing a challenge in enhancing storage capacity and power-saving performance.
Innovation Solution
A transmission circuit comprising a comparison module and a data conversion module that compares data on two lines and inverts data when the difference exceeds a preset threshold, reducing power consumption by minimizing data inversions while maintaining transmission accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the density and number of memory cells are increased, then the storage capacity is improved, but the power consumption of the data transmission path increases
Solution Approach 1:
The patent changes the transmission mode parameter by selectively switching between inverted and non-inverted data transmission based on the comparison result. This parameter change reduces the number of data inversions needed, thereby lowering the power consumption of the data transmission path while maintaining the ability to transmit data across increased memory cell densities
2Quantity of substance
If the number of memory cells is increased, then the storage capacity is improved, but the length of the data transmission path increases
Solution Approach 1:
The patent segments the data transmission process into two paths: one for inverted data and one for non-inverted data. By comparing the first data with second data and selectively routing through different paths based on whether the bit difference exceeds a threshold, the system handles longer transmission paths more efficiently without requiring uniform inversion of all data

AI summary
Embodiments relate to a transmission circuit, a transmission method, a storage apparatus, and a storage medium. The transmission circuit includes a comparison module and a data conversion module. The comparison module is configured to receive first data on a first data line and second data on a second data line, and compare the first data with the second data to output a comparison result indicating whether number of different bits between the first data and the second data exceeds a preset threshold, wherein the first data and the second data have the same preset bit width. The data conversion module is electrically connected to the first data line, the comparison module and the second data line, and is configured to invert the first data and transmit the inverted first data to the second data line when the comparison result is indicative of exceeding the preset threshold.
