Nonvolatile Memory Management Information Restoration for Activation Failures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information processing apparatuses with nonvolatile memory devices face challenges in diagnosing and resolving malfunctions, particularly when the program is broken or the device is physically damaged, leading to inefficient troubleshooting and potential waste of time during the download process.
Innovation Solution
The apparatus incorporates a nonvolatile memory device with management information that restores abnormality detection at activation, a reactivation unit to restart the system, and a processing unit to differentiate between program and physical damage issues based on abnormality detection, prompting either program download or device replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the program is downloaded again to a physically damaged nonvolatile memory device, then the download process is completed, but the malfunction cannot be solved and time is wasted
Solution Approach 1:
The patent applies preliminary action by detecting whether the nonvolatile memory device is physically damaged before initiating the program download process. The determination unit performs this check in advance, and only allows download when the device is confirmed to be functional. This prevents wasting download time on physically damaged devices and ensures that the download resource is allocated only when it can be effective.
2Productivity
If the apparatus automatically reactivates when activation stops part way through, then reactivation may succeed, but the cause of the stoppage is not identified
Solution Approach 1:
The patent implements feedback by having the determination unit continuously monitor the activation process and detect the cause of stoppage. When activation stops part way through, the system provides feedback about the detected cause (program broken or physical damage) and takes appropriate action - either reactivating the apparatus or notifying the service person. This feedback loop ensures both rapid reactivation when possible and proper diagnostic information capture when needed.

AI summary
An information processing apparatus includes a nonvolatile memory device in which a program for activating the apparatus is stored, and which has a function of, in a case where an abnormality of management information indicating a correspondence relationship between a logical address and a physical address for data stored in the memory device is detected, performing a process of restoring the an abnormality of the management information is detected at a time of activation of the memory device. In a case where activation of the apparatus based on the program stops part way through, the apparatus is reactivated. Different processes for solving a malfunction in which activation of the apparatus stops part way through are executed based on whether or not an abnormality of the management information is detected in the memory device after the reactivation.
