Memory Chip Recovery Through Independent Reset for Redundant Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Memory failures in servers often lead to system breakdowns due to the lack of redundant memory chips, resulting in uncorrectable errors and the need for hardware replacement or system reboot.
Innovation Solution
A method and system for memory fault recovery that involves a processor locating faulty memory chips, isolating or replacing them, and resetting them independently without affecting other chips, using a chip reset circuit or the processor's pins to restore the faulty chips to a normal state, ensuring redundant memory capacity is maintained.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a faulty memory chip is replaced with a redundant memory chip, then the system can continue to operate, but the redundant memory chip is consumed and cannot be reused, leading to system breakdown when no redundant chips remain
Solution Approach 1:
The patent applies the discarding and recovering principle by resetting the faulty memory chip to restore it to a usable state. Instead of permanently replacing the faulty chip with a redundant one and discarding the faulty chip, the system resets the faulty chip to recover its functionality, allowing it to be reused as a working memory chip.
Solution Approach 2:
The patent applies parameter changes by altering the operational state of the faulty memory chip through reset operations. The chip transitions from a faulty state to a restored state by changing its internal parameters and state, enabling it to function normally again without physical replacement.
2Reliability
If the entire memory system is reset when a fault occurs, then the faulty chip can be restored, but all other memory chips are also reset which affects normal operations
Solution Approach 1:
The patent applies segmentation by isolating the faulty memory chip from the rest of the memory system. The system identifies and separates the specific faulty chip, allowing reset operations to be applied only to that chip rather than the entire memory system, thus preventing disruption to other functioning chips.
Solution Approach 2:
The patent extracts the faulty memory chip from the operational memory system by isolating it. This extraction allows the faulty chip to be reset independently without affecting the normal operations of other memory chips, maintaining system productivity during the recovery process.
3Reliability
If memory chips are continuously monitored for faults, then early detection is possible, but system complexity increases
Solution Approach 1:
The patent applies feedback by implementing continuous monitoring of memory chip status and using this information to trigger appropriate responses. The system monitors for faults and provides feedback to initiate reset operations when needed, creating a closed-loop system that maintains reliability through automated detection and recovery.

AI summary
A system includes a processor and a memory. The processor locates a first memory chip that is faulty in a memory. After the first memory chip is isolated or replaced, the processor may reset the first memory chip when other memory chips in the memory are maintained to work normally. When a fault occurs in a memory chip in the memory, after the first memory chip that is faulty is isolated or replaced, the processor may independently reset the first memory chip without affecting the other memory chips in the memory. Resetting the first memory chip enables the first memory chip to restore to normal. A memory chip that can be normally used is used as a redundant memory chip or may continue to be used.
