Buffer Chip Memory Segmentation Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing memory capacity requirements of computers, particularly servers, are hindered by the reduction in memory module slots due to industry trends like higher memory bus speeds and small form factor machines, while large capacity memory modules are cost-prohibitive, necessitating a cost-effective approach to enhance memory capacity.
Innovation Solution
A system and method involving multiple smaller capacity memory circuits, where a power-saving operation is performed by identifying inactive memory circuits and delaying signal communication to them, using a buffer chip to simulate a larger capacity memory circuit and manage power consumption effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple smaller capacity memory circuits are used instead of a single large capacity memory circuit, then cost is reduced and adaptability is improved, but device complexity increases due to the need for additional control logic and signal routing
Solution Approach 1:
A buffer chip is introduced as an intermediary component between the memory controller and multiple smaller memory circuits. The buffer chip contains control logic that manages signal distribution, timing coordination, and power saving operations across the multiple memory circuits, thereby reducing the complexity burden on the main memory controller while enabling flexible memory capacity configuration
Solution Approach 2:
The memory system is segmented into multiple independent smaller capacity memory circuits instead of using a single large capacity circuit. This segmentation allows for cost-effective memory expansion and better adaptability to different capacity requirements, while the buffer chip coordinates these segmented circuits to function as a unified memory system
2Use of energy by moving object
If power saving operations are performed by placing memory circuits in idle state, then power consumption is reduced, but signal timing and communication coordination become more complex
Solution Approach 1:
The buffer chip performs preliminary actions by anticipating memory access patterns and proactively placing idle memory circuits into power saving states before they are needed. It also pre-coordinates signal timing and prepares data buffering in advance, allowing memory circuits to be switched between active and idle states without causing timing conflicts or communication errors
Solution Approach 2:
The buffer chip acts as a mediator that manages the transition between active and idle states for multiple memory circuits. It handles the complex signal timing coordination required for power saving operations, absorbing the coordination complexity within the buffer chip itself while presenting a simplified interface to the memory controller
