Solution Overview
Problem
Existing memory sub-systems face challenges in efficiently managing data throughput and heat dissipation, particularly when the internal temperature of memory devices or controllers exceeds 85 degrees Celsius, leading to throttling of data throughput and reduced performance.
Innovation Solution
The implementation of a thermally conductive material (TCM) that is physically and thermally coupled to memory components, acting as a heat sink to dissipate heat while maintaining compliance with height restrictions on printed circuit boards, thereby controlling data throughput based on temperature thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data throughput is increased in memory sub-systems, then productivity is improved, but temperature increases causing throttling and reduced performance
Solution Approach 1:
A thermally conductive material (TCM) is introduced as an intermediary substance between the memory components and the heat sink. The TCM fills voids and improves thermal contact, enabling more efficient heat transfer from the memory sub-system components to the heat dissipation structure, thereby allowing sustained high data throughput without excessive temperature rise
Solution Approach 2:
The patent changes the thermal parameters of the system by introducing a material with high thermal conductivity (TCM) into the thermal pathway. This parameter change enhances the overall heat transfer coefficient, allowing the system to dissipate heat more effectively and maintain lower operating temperatures during high-performance operation
2Temperature
If heat dissipation structures are added to memory sub-systems, then temperature control is improved, but device complexity increases
Solution Approach 1:
The thermally conductive material serves multiple functions simultaneously: it acts as a thermal interface material for heat dissipation, a filler to eliminate voids in the packaging structure, and a structural element that maintains component spacing. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity while improving temperature control
3Temperature
If thermally conductive material is deposited on PCB, then heat dissipation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The thermally conductive material is applied selectively at specific locations on the PCB where thermal interface is needed, rather than uniformly across the entire board. This localized application approach allows for targeted heat dissipation enhancement while reducing the overall manufacturing precision requirements compared to full-coverage deposition
