Dynamic Storage Region Parameter Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Storage devices face inefficiencies due to dynamic changes in storage region operating parameters, which require frequent updates and certification, leading to performance loss and additional wear when storing this information away from the storage region.
Innovation Solution
Implement a method to iteratively update and store operating parameters of storage regions during operation, allowing these values to be used directly within the storage region for access, reducing the need for frequent central location access and minimizing wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If operating parameters are stored in a central location away from storage regions, then device complexity is reduced, but access efficiency deteriorates and wear increases due to frequent updates
Solution Approach 1:
The patent divides the storage device into multiple storage regions, each with its own locally stored operating parameters. This segmentation allows each region to be managed independently with its own parameter set, eliminating the need for frequent centralized access while maintaining organized management through region-specific metadata areas.
Solution Approach 2:
Operating parameters are stored locally within or near each storage region rather than in a centralized location. This local quality approach ensures that parameter updates and accesses occur close to the data they describe, improving access efficiency and reducing the impact on overall device performance.
2Measurement precision
If operating parameters are updated frequently to reflect dynamic changes, then measurement precision is improved, but device wear increases due to repeated write operations
Solution Approach 1:
The patent performs preliminary characterization of storage regions during manufacturing or initial use, establishing baseline operating parameters before normal operation begins. This preliminary action reduces the need for frequent updates during normal operation, thereby minimizing wear while maintaining accurate parameter values.
Solution Approach 2:
Instead of continuous or frequent parameter updates, the system implements periodic characterization and parameter updates at defined intervals or under specific conditions. This periodic approach maintains measurement precision by updating parameters when necessary while reducing overall update frequency to minimize device wear.
3Reliability
If storage regions are certified before use, then reliability is improved, but productivity deteriorates due to time-consuming certification processes
Solution Approach 1:
Storage regions undergo preliminary certification and characterization during manufacturing or initial setup, with operating parameters established before the regions are put into service. This preliminary action ensures reliability through proper certification while reducing the time required during normal operation, as regions are already validated and ready for use.
