Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information handling systems face challenges in managing and upgrading memory expansion capabilities, as memory modules are often permanently configured with expansion functions at the manufacturing level, limiting flexibility and requiring users to replace modules for additional functionality, especially in large-scale environments like data centers where centralized management is desirable.

The implementation of a cryptographic framework within the information handling system that creates and manages expansion capability certificates, allowing for the secure unlocking and binding of memory module functions to specific systems, enabling dynamic management and upgrade of memory expansion capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If memory modules are permanently configured with expansion functions at manufacturing level, then manufacturing simplicity is maintained, but system flexibility and adaptability are reduced
Solution Approach 1:
The patent applies preliminary action by pre-configuring memory modules with expansion capability certificates during manufacturing, but keeping the expansion functions locked until authenticated. This allows manufacturers to prepare modules in advance while deferring the actual enabling of expansion functions to a later authentication stage, thus maintaining manufacturing simplicity while enabling system flexibility.
Solution Approach 2:
The patent implements dynamics by transitioning memory module configuration from a static permanent state to a dynamic conditional state. Expansion functions are not fixed at manufacturing but can be dynamically enabled or disabled based on authentication results, allowing the system to adapt to different operational requirements while maintaining a simple manufacturing process.
2Device complexity
If memory modules require replacement for additional functionality, then device complexity is reduced, but productivity and loss of time increase
Solution Approach 1:
The patent applies copying by using cryptographic certificates to replicate authentication credentials between systems. Instead of replacing physical memory modules, the system can copy or transfer expansion capability certificates to enable the same expansion functions on different modules, dramatically improving productivity while maintaining manageable device complexity.
Solution Approach 2:
The patent introduces an intermediary mechanism - the expansion capability certificate - that mediates between the memory module and the processing system. This certificate acts as a key that can be transferred or copied, allowing expansion functions to be enabled without physical module replacement, thus improving productivity while keeping the system relatively simple to manage.
3Adaptability or versatility
If memory modules are configured with expanded functions, then adaptability is improved, but manufacturing precision and reliability requirements increase
Solution Approach 1:
The patent replaces mechanical configuration methods with cryptographic authentication. Instead of physically configuring or hardwiring expansion functions, the system uses digital certificates and cryptographic verification to control function enabling. This substitution maintains high adaptability while reducing manufacturing precision requirements, as cryptographic operations are more tolerant of manufacturing variations than physical configuration methods.
4Adaptability or versatility
If centralized management of memory functions is implemented, then adaptability and system-level control are improved, but device complexity increases
Solution Approach 1:
The patent applies universality by designing the expansion capability certificate to serve multiple functions: authentication, authorization, and configuration management. This single cryptographic mechanism enables centralized control across diverse memory modules and systems without requiring separate complex management mechanisms for each function, thus improving adaptability while limiting the increase in device complexity.
Data Source
AI summary
An information handling system includes a processor and a memory module. The memory module operates with a base set of functions and is configurable to operate with an expanded set of functions. The memory module includes a data storage location to store expansion capability certificates that specify subsets of the expanded set of functions to enable. The processor creates an expansion capability certificate that includes a first unique identifier of the information handling system, a second unique identifier of the memory module, and a subset of the expanded set of functions, and provides the expansion capability certificate to the memory module. The memory module receives the first expansion capability certificate, stores the expansion capability certificate to the data storage location, and enables the subset of the expanded set of functions in response to storing the expansion capability certificate.
