Memory Operation Performance Limits for Uniform Host-Controlled Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Variations in performance characteristics among memory apparatuses from different manufacturers lead to non-uniform performance in electronic devices, causing unpredictable user experiences, increased complexity in system management, and potential component stress or failure.
Innovation Solution
Implementing host configured performance limits by setting standardized performance thresholds for memory operations based on capability information, allowing the memory apparatus to adjust its operations to meet these limits, thereby ensuring uniform performance across devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If memory apparatuses operate at their maximum performance capabilities, then productivity is improved, but reliability deteriorates due to increased stress and overheating
Solution Approach 1:
The patent implements dynamic performance limits that can be adjusted based on host system requirements and memory apparatus capabilities. The host system configurable performance limits allow the memory apparatus to operate at optimized performance levels rather than always at maximum capacity, enabling flexible adaptation between speed and reliability based on current system needs
Solution Approach 2:
The patent changes operational parameters by introducing configurable performance limits that constrain memory operation speeds and throughput. These parameter adjustments allow the system to operate at lower, more reliable performance levels when needed, while still achieving high productivity when performance limits are set higher
2Adaptability or versatility
If memory apparatuses from different manufacturers are used, then adaptability is improved, but performance uniformity deteriorates
Solution Approach 1:
The patent creates a universal performance limiting mechanism that works across memory apparatuses from different manufacturers. The host system configurable performance limits provide a common interface and control method that standardizes performance regardless of the specific manufacturer or model, enabling the system to universally manage diverse memory components
Solution Approach 2:
The patent implements feedback through capability information exchange between the memory apparatus and host system. The memory apparatus provides capability information about its performance characteristics, and the host system uses this feedback to configure appropriate performance limits, creating a closed-loop system that ensures uniform performance across different manufacturers
3Reliability
If performance limits are set lower to ensure reliability, then component stress is reduced, but productivity decreases
Solution Approach 1:
The patent makes performance limits dynamic and configurable rather than fixed. The host system can adjust performance limits based on current workload requirements, allowing the system to operate at higher productivity levels when reliability concerns are minimal and at lower levels when stability is prioritized
Solution Approach 2:
The patent applies partial action by setting performance limits that are sufficient for the required workload but not necessarily at maximum capacity. This allows the system to use only the portion of memory performance needed for current tasks, reducing unnecessary stress while maintaining adequate productivity
Data Source
AI summary
In some implementations, a memory apparatus may transmit, to a host system, capability information indicating one or more supported memory operations of the memory apparatus. The memory apparatus may receive, from the host system, configuration information indicating one or more performance limits for at least one supported memory operation of the one or more supported memory operations.
