Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data access methods for multiple storage devices are limited by the read and write performance of individual storage devices, making it challenging to effectively access them without altering their performance characteristics.
Innovation Solution
A data access method that determines a target access mode for multiple storage devices based on data access requests, utilizing access control signals to differentiate between high-security and high-speed access modes, allowing for efficient access without changing the storage devices' performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the access device accesses the storage device based on the read and write performance of the storage device, then the data access is limited by the storage device performance, but the access device can ensure stable and reliable data access
Solution Approach 1:
The patent implements dynamic access mode selection between first access mode and second access mode based on real-time access scenarios. The controller dynamically adjusts access control signals and timing parameters according to the specific data access requirements, enabling the system to adaptively optimize access efficiency without fixed performance limitations
Solution Approach 2:
The patent changes access control parameters such as timing signals, control signal sequences, and access mode selections to achieve different access performances. By modifying these parameters, the system can exceed the traditional read and write performance limits of the storage device while maintaining stable and reliable data access
2Speed
If multiple storage devices are accessed simultaneously, then the access speed can be improved, but the access security and reliability may be compromised
Solution Approach 1:
The patent segments the access control into different modes (first access mode and second access mode) with distinct security and speed characteristics. By dividing the access control strategy into multiple specialized modes, the system can simultaneously achieve high-speed access when needed and high-security access when required, resolving the contradiction between speed and reliability
Solution Approach 2:
The system dynamically switches between different access modes based on the specific access scenario. When security is prioritized, the first access mode is used; when speed is prioritized, the second access mode is used. This dynamic adaptation allows the system to achieve both high speed and high reliability in different contexts

AI summary
A data access method includes obtaining a data access request for M storage devices, M being an integer greater than or equal to 2, determining a target access mode for the M storage devices based on the data access request, and performing data access on the storage devices based on access control signals matching the target access mode for the storage devices. The target access mode includes a first access mode and a second access mode. Access security and/or access speed generated when the data access is performed on the storage devices in the first access mode is different from access security and/or access speed generated in the second access mode.
