Memory Sub-System Temperature Regulation via Dynamic Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing memory sub-systems face challenges in dynamically regulating temperature, particularly during save and restore operations, which can lead to increased temperatures beyond acceptable limits.
Innovation Solution
Incorporating a temperature component within the memory sub-system or its controller that monitors temperature values and adjusts data transfer parameters, such as data size or transfer speed, to maintain temperatures within a safe range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data transfer operations are performed at high speed in memory sub-systems, then productivity is improved, but temperature increases beyond acceptable limits
Solution Approach 1:
The patent implements dynamic temperature regulation by continuously monitoring temperature values and adjusting data transfer parameters in real-time. The system transitions from static to dynamic operation, modifying data size or transfer speed based on current temperature conditions to maintain temperatures within acceptable limits while maximizing productivity.
Solution Approach 2:
The system changes operational parameters (data size, transfer speed) based on temperature thresholds. When temperature exceeds acceptable limits, the system modifies these parameters to reduce thermal generation, directly addressing the contradiction between high-speed operation and temperature control.
2Productivity
If data size is increased to improve throughput, then productivity is improved, but temperature increases beyond acceptable limits
Solution Approach 1:
The system dynamically adjusts data size based on temperature feedback. Instead of using a fixed data size for all operations, the system modifies the data size parameter in response to temperature conditions, allowing high throughput when temperatures are acceptable and reducing data size when temperatures approach limits.
Solution Approach 2:
The patent incorporates temperature monitoring and feedback mechanisms that inform subsequent data transfer decisions. The system uses temperature threshold comparisons to feedback control the selection of data size, creating a closed-loop system that balances throughput and temperature.

AI summary
A method includes determining, by a first component of a memory sub-system controller, a first temperature value of the memory subsystem controller. The method can further include determining, by a second component of a non-volatile memory device, a second temperature value of the non-volatile memory device coupled to the memory sub-system controller. The method can further include modifying a data parameter in response to at least one of the first temperature value or the second temperature value exceeding a threshold temperature value.
