Memory Thermal Voltage Model Switching for Lower Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Memory devices in portable electronic devices experience reduced performance and increased power consumption due to broad thermal voltage model configurations, which are not aligned with actual operating conditions, leading to higher latency and power consumption.
Innovation Solution
A memory system is configured with an initial thermal voltage model for a broad range of potential conditions and subsequently reconfigured with a narrower model based on actual operational conditions, monitored over time, to enhance performance and reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a broad thermal voltage model is configured for memory devices, then the memory system can operate across a wide range of potential conditions, but performance is reduced and power consumption increases
Solution Approach 1:
The patent applies dynamics by transitioning from a static broad thermal voltage model to a dynamic model selection process. The system initially operates with a first thermal voltage model covering a broad temperature range, then monitors actual operating conditions and switches to a second thermal voltage model with a narrower temperature range that better matches actual conditions. This dynamic adaptation resolves the contradiction by allowing the system to maintain broad adaptability when needed while achieving optimized performance when actual conditions are known.
Solution Approach 2:
The patent applies parameter changes by modifying the thermal voltage model parameters based on monitored operating conditions. The system changes from using a first set of thermal voltage model parameters (broad temperature range) to a second set of parameters (narrower temperature range) that are better suited to actual operating conditions. This parameter optimization resolves the contradiction between broad adaptability and high performance by adjusting parameters to match actual usage scenarios.
2Adaptability or versatility
If a broad thermal voltage model is configured for memory devices, then the memory system can operate across a wide range of potential conditions, but power consumption increases
Solution Approach 1:
The system dynamically adjusts its thermal voltage model based on monitored operating conditions, switching from a broad-coverage model that consumes more power to a narrower, more efficient model when actual conditions are known. This dynamic approach resolves the contradiction by maintaining adaptability when needed while reducing power consumption during stable operation.
Solution Approach 2:
The system changes thermal voltage model parameters from a broad temperature range configuration to a narrower, optimized configuration based on actual operating conditions. This parameter optimization reduces power consumption while maintaining the necessary operating range, resolving the contradiction between adaptability and energy efficiency.
3Productivity
If operation is monitored over a period of time to select a narrower thermal voltage model, then performance and power efficiency improve, but system complexity increases
Solution Approach 1:
The patent applies feedback by monitoring actual operating conditions over time and using this information to select an appropriate thermal voltage model. The system continuously observes temperature and operational parameters, then switches from a first thermal voltage model to a second, more optimized model based on the monitored data. This feedback mechanism resolves the contradiction by automating the model selection process, making the added complexity worthwhile through significant performance improvements.
4Loss of time
If a narrower thermal voltage model is selected based on monitored operation, then latency is reduced and power consumption decreases, but the initial configuration and monitoring overhead increase
Solution Approach 1:
The patent applies preliminary action by first configuring the system with a conservative first thermal voltage model that covers a broad temperature range, ensuring reliable operation during the initial period. During this time, the system monitors actual operating conditions to gather data. This preliminary configuration approach resolves the contradiction by ensuring system reliability during the monitoring phase while preparing for optimized operation once sufficient data is collected.
Solution Approach 2:
The system uses feedback from monitored operating conditions to determine when to switch from the first thermal voltage model to a second, optimized model. This feedback-driven approach resolves the contradiction by automatically managing the transition based on actual performance data, reducing latency and power consumption once the optimal model is selected.
