Memory Fault Event Registers for Real-Time Host Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Memory systems often fail to communicate fault conditions to the host system, leading to inefficiencies, increased risk of hacking, and compromised security and safety, as well as decreased performance and increased power consumption.
Innovation Solution
Implementing a mechanism for real-time fault condition detection and communication to the host system through a register and message transmission, allowing for immediate remedial actions and preventing time-out conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real-time fault detection and communication mechanism is implemented, then reliability and security are improved, but device complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the memory system continuously monitors its operational status through event registers and communicates fault conditions to the host system in real-time. The host system receives interrupt signals and error status information, enabling it to respond immediately to memory faults without waiting for timeout conditions, thus improving reliability through continuous monitoring and communication loops.
Solution Approach 2:
The patent employs preliminary action by pre-configuring event registers and interrupt mechanisms that are ready to detect and communicate faults immediately when they occur. The memory system is pre-programmed with error detection logic and communication protocols, allowing it to proactively notify the host system of potential issues before they escalate into system failures or security breaches.
2Loss of time
If real-time fault communication is implemented, then latency is reduced and performance is improved, but use of energy increases
Solution Approach 1:
The patent implements periodic action through scheduled status register checks and interrupt-driven communication rather than continuous monitoring. The host system periodically queries memory status registers or receives interrupts only when fault conditions are detected, allowing the memory system to enter low-power states between monitoring events while maintaining the ability to quickly detect and communicate errors when they occur.

AI summary
Methods, systems, and devices for error detection event mechanism are described. The memory system may identify a fault condition and transmit, to a host system, a message indicating a first indication that the fault condition exists at the memory system. In some cases, the memory system may set, in a register of the memory system, a second indication indicating a type of the fault condition based on identifying the fault condition. The memory system may perform a recovery procedure based on the first indication and the second indication.
