Memory Module Power-Line Sharing for Uniform Device Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dual in-line memory modules face challenges in uniformly providing power to memory devices due to varying distances and performance differences, leading to inefficient power management.
Innovation Solution
A memory module with a module substrate that includes a first power line for external power supply and a second power line connecting power management members of adjacent memory devices, allowing for power sharing and management among these devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single PMIC is used to supply power to multiple packages, then the power management structure is simple, but uniform power distribution to all packages cannot be achieved due to distance and performance differences
Solution Approach 1:
The patent divides the power management function into multiple power management members, each associated with specific memory devices. Instead of using a single centralized PMIC, the system segments power management across multiple distributed units (power management members 200-1, 200-2, etc.), allowing each to independently manage power for nearby devices and achieve uniform power distribution.
Solution Approach 2:
The patent implements local power management where each power management member is positioned close to the memory devices it serves, enabling localized power control and compensation for distance-related power loss. This local quality approach ensures that each package receives appropriate power levels tailored to its specific requirements.
2Device complexity
If power is supplied from a single source to all memory devices, then the power supply system is simple, but rapid power response during high-power operations cannot be achieved
Solution Approach 1:
The power supply system is segmented into multiple independent power management members that can respond simultaneously to power requirements of different memory devices. This segmentation enables parallel power response, where each power management member independently detects and responds to power needs of its associated devices without waiting for centralized control.
Solution Approach 2:
Each power management member is equipped with autonomous power management capabilities, including internal voltage generation and power control functions. This self-service approach allows each power management member to independently detect power requirements and adjust power supply without external intervention, achieving rapid power response during high-power operations.

AI summary
A memory module includes a module substrate, a plurality of memory devices, a first power line, and a second power line. The memory devices are mounted on the module substrate. Each of the memory devices includes a power management member. The first power line may be arranged in the module substrate to provide each of the memory devices with power. The second power line may be electrically connected between the power management members of adjacent memory devices to control and share the power provided to the adjacent memory devices.
