Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional storage applications using nonzero initial offsets are incompatible with systems that use zero-based memory management, leading to separate architectures and processes for handling memory, which complicates memory management across different applications.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate memory management architectures are used for conventional storage applications (zero-based) and other applications (nonzero initial offsets), then compatibility and reliability for each application type is improved, but device complexity increases
Solution Approach 1:
The patent merges separate memory management architectures into a unified architecture that can handle both zero-based and nonzero initial offset applications through a common set of data structures and algorithms. The CDB (Command Descriptor Block) structure is designed to accommodate both types of applications using a union type that can store either a steering tag (for zero-based) or a virtual address (for nonzero initial offsets), eliminating the need for separate management systems.
Solution Approach 2:
The memory management system achieves universality by designing the CDB structure and associated algorithms to serve multiple application types simultaneously. The system can dynamically determine whether to use zero-based or nonzero initial offsets based on the application type, allowing a single memory management system to universally handle both conventional storage applications and other applications without requiring separate architectures.
2Ease of operation
If separate memory management systems are maintained for different application types, then ease of operation for each specific application is improved, but adaptability across different applications deteriorates
Solution Approach 1:
The memory management system employs dynamic behavior by including a flag field in the CDB structure that indicates whether the application uses zero-based or nonzero initial offsets. This dynamic indication allows the system to automatically adjust its behavior based on the application type, maintaining ease of operation for each specific application while achieving adaptability across different applications through a single unified system.
3Manufacturing precision
If distinct memory structures and algorithms are used for different application types, then manufacturing precision for each application type is improved, but ease of manufacture of the memory management system deteriorates
Solution Approach 1:
The patent applies parameter changes by modifying the CDB structure to include a union type that can represent different offset types, and by using a flag field to indicate the current offset type being used. This parameter-based approach allows the system to maintain manufacturing precision for each application type while improving ease of manufacture, as the same data structure and algorithms can be used for both application types by simply changing the parameter (offset type) based on the flag value.
