Dual-Controller Flash-Memory Bridge for Storage Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bridge devices are unable to support high-speed transmission interfaces made by different processes or in compliance with different standards, leading to compatibility issues between host devices and newly developed data storage devices, preventing access and authentication.
Innovation Solution
A bridge device is designed with dual controllers, each equipped with transmission interfaces and control units, capable of communicating through different standards, allowing it to act as a mediator between host and data storage devices, ensuring compatibility and enabling access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data storage devices are developed using the latest process or standard, then performance and manufacturing cost are improved, but compatibility with existing bridge devices deteriorates
Solution Approach 1:
The bridge device is designed with dual controllers, where each controller can support different transmission interface standards (e.g., first standard and second standard). This multi-functionality allows a single bridge device to accommodate data storage devices developed with different processes or standards, resolving the contradiction between using latest technologies and maintaining compatibility.
Solution Approach 2:
The bridge device acts as an intermediary between host devices and data storage devices with different standards. By incorporating multiple transmission interface standards in the bridge device, it mediates communication between devices with incompatible interfaces, enabling the host to access newly developed data storage devices that use latest processes or standards.
2Adaptability or versatility
If a single bridge device supports multiple transmission interface standards, then compatibility is improved, but device complexity increases
Solution Approach 1:
The bridge device is segmented into multiple independent controllers, where each controller is responsible for a specific transmission interface standard. This segmentation allows each controller to be optimized for its specific function while collectively providing multi-standard support, managing complexity through modular design rather than requiring a single complex controller to handle all standards.

AI summary
A bridge device includes a first controller and a second controller. The first controller includes a first transmission interface. The second controller is coupled to the first controller and includes a second transmission interface coupled to the first transmission interface. The first transmission interface and the second transmission interface are both flash memory interface.
