Memory System Thermal Voltage Model Selection for Lower Latency and Power Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Memory devices in mobile/portable electronic devices experience performance degradation and increased power consumption due to broad thermal voltage model configurations, which are not optimized for 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 thermal voltage 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 degrades and power consumption increases
Solution Approach 1:
The patent implements dynamic thermal voltage model selection that adapts the memory system's operating characteristics based on actual runtime temperature conditions. The system transitions from a static broad-range model to a dynamic model that selects appropriate thermal voltage characteristics based on monitored temperature, thereby maintaining optimal performance across varying conditions without the penalties of a permanently conservative broad-range configuration.
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 power consumption by selecting thermal voltage models matched to actual operating temperatures. Instead of maintaining the higher power consumption required by a broad-range model, the system transitions to temperature-appropriate models that reduce power usage while maintaining operational capability across the temperature range.
3Adaptability 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 latency increases
Solution Approach 1:
The patent reduces latency by dynamically selecting thermal voltage models based on actual operating conditions. The system monitors temperature and transitions from a conservative broad-range model that introduces latency to a temperature-optimized model that minimizes access time while maintaining reliability within the observed temperature range.
