Data Transmission Circuit with Selective Pass Sections for Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current semiconductor memory systems face inefficiencies in data transmission due to the lack of optimized data loading paths, leading to increased power consumption and operation time, particularly in volatile memory applications where data is frequently written and read.
Innovation Solution
A data transmission circuit with pass sections and a pass control unit that selectively enables or disables data line connections based on addresses to form optimal data transmission paths, reducing power consumption and operation time by controlling data loading lengths on data line groups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If data line groups are connected without selective pass sections, then data transmission path is simple, but power consumption increases and operation time increases
Solution Approach 1:
The data transmission circuit is segmented into multiple data line groups (first data line group, second data line group, etc.) with separate pass sections controlling each group's connection to the bit line group. This segmentation allows selective activation of only the necessary data line groups for current operations, reducing overall power consumption while maintaining the ability to form complete transmission paths when needed.
Solution Approach 2:
The pass sections are made dynamically controllable through pass control signals that change the connection state of data line groups based on operational requirements. This dynamic reconfiguration enables the system to adapt the data transmission path in real-time, connecting only the necessary data line groups for current read/write operations, thereby reducing power consumption and operation time without sacrificing transmission capability.
2Loss of time
If all data line groups are always connected, then data transmission path is always available, but operation time increases due to unnecessary data loading
Solution Approach 1:
The pass control unit预先 determines which data line groups need to be connected based on the current operational mode (read or write) and activates only those specific pass sections in advance. This preliminary selection prevents unnecessary data loading operations and reduces operation time while ensuring that the required data transmission paths are already established when needed, maintaining transmission reliability.
Solution Approach 2:
Different data line groups are assigned different connection states based on their specific functional requirements in each operational mode. Instead of uniformly connecting all data line groups, the system applies local connection quality control where only the necessary data line groups are activated, optimizing both operation time and transmission availability for each specific task.
3Productivity
If pass sections are selectively enabled based on address, then data loading efficiency improves, but device complexity increases
Solution Approach 1:
The pass control unit serves multiple functions: it decodes the address signal, determines the operational mode (read/write), selects the appropriate data line groups, and generates the corresponding pass control signals. This multi-functional design consolidates control logic into a single unit, improving data loading efficiency without proportionally increasing overall device complexity.
Solution Approach 2:
The pass control unit acts as an intermediary between the address input and the data line group connections. It translates the address signal into specific pass control signals that enable selective activation of pass sections, thereby improving data loading efficiency while distributing the complexity management to a dedicated control layer rather than embedding it throughout the entire data transmission circuit.

AI summary
A data transmission circuit may include data line groups and pass sections arranged among the data line groups to allow the data line groups to form one line. The data transmission circuit may include an input/output unit configured to be coupled to the data line groups and to process write data to be transmitted to the data line groups or read data transmitted from the data line groups. The data transmission circuit may include a pass control unit configured to selectively enable the pass sections in response to an address for specifying a target data line group of the data line groups.
