Solution Overview
Problem
Existing memory systems face inefficiencies in temperature mitigation techniques, as they often reduce processing speed across all components, including those not experiencing high temperatures, due to uneven access operations, leading to suboptimal performance.
Innovation Solution
Implementing a system with distributed temperature sensors to monitor and model temperatures, allowing for targeted mitigation techniques such as adjusting clock frequencies and data transfer strategies for high-temperature sections while maintaining separate clock frequencies for other sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If temperature mitigation techniques are applied to reduce high temperatures in memory systems, then temperature control is improved, but processing speed of all components is reduced including those not experiencing high temperatures
Solution Approach 1:
The patent divides the memory system into multiple sections, each with its own temperature sensor and clock frequency control. This allows independent temperature monitoring and mitigation for each section, so that only high-temperature sections receive mitigation while other sections maintain full processing speed. The segmentation enables localized temperature control without system-wide performance degradation.
Solution Approach 2:
The patent implements local temperature mitigation by applying temperature control measures only to specific sections experiencing high temperatures. Each section has its own temperature sensor and can independently adjust its clock frequency based on local temperature conditions. This ensures that processing speed is maintained in cool sections while temperature is controlled in hot sections, resolving the contradiction between temperature control and overall productivity.
2Temperature
If clock frequency is reduced to mitigate temperature, then temperature control is improved, but system performance deteriorates
Solution Approach 1:
The patent implements dynamic clock frequency adjustment where each section's clock frequency is continuously adapted based on real-time temperature sensor readings. When a section's temperature exceeds a threshold, its clock frequency is reduced; when temperature is within acceptable ranges, full frequency is maintained. This dynamic approach optimizes the balance between temperature mitigation and system performance by making frequency adjustments responsive to actual thermal conditions rather than applying static reductions system-wide.
Solution Approach 2:
The patent changes the operational parameters (clock frequency) of individual memory sections based on their temperature conditions. By monitoring temperature sensors in each section and adjusting the clock frequency parameter locally, the system achieves temperature mitigation only where needed while maintaining optimal performance parameters in cooler sections, thus resolving the contradiction between temperature control and overall system performance.

AI summary
Methods, systems, and devices for adaptive temperature protection for a memory controller are described. In some cases, a memory system may include a set of temperature sensors distributed across the memory system. The set of temperature sensors may be used to monitor or model the temperature of one or more sections of the memory system. Upon determining that the temperature of a section exceeds a threshold, the memory system may employ one or more mitigation techniques to reduce the temperature or the rate of change of the temperature of the section. For example, the memory system may reduce a clock frequency corresponding to the section, while maintaining separate clock frequencies for other sections of the memory system. Additionally or alternatively, the memory system may transfer data or other information from the section to a separate section.
