Memory Control Circuit Unit for Non-Volatile Storage Failure Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The lack of an integrated memory operation monitoring mechanism leads to frequent execution failure events in rewritable non-volatile memory modules, due to violations of operation specifications such as sequential memory address usage and prior command execution.
Innovation Solution
A memory operation control method and circuit unit that establish management data with status recording, allowing determination of whether to execute operation commands based on query results, thereby ensuring compliance with operation specifications and reducing failure events.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no integrated memory operation monitoring mechanism is implemented, then the device complexity is reduced, but the execution failure events increase frequently
Solution Approach 1:
The patent applies preliminary action by establishing management data and status recording data before memory operations are executed. The monitoring mechanism proactively tracks the execution status of previous commands and memory address usage patterns in advance, allowing the system to predict and prevent potential execution failures before they occur, rather than reacting after failures happen.
Solution Approach 2:
The patent implements feedback by continuously monitoring memory operation status and using this information to control subsequent operations. The management circuit queries status recording data to determine whether to allow execution of operation commands, creating a closed-loop control system where past operation results directly influence future operation decisions, thereby improving execution reliability.
2Reliability
If operation commands are executed without monitoring, then the working efficiency appears high, but execution failure events occur frequently
Solution Approach 1:
The system performs preliminary checks by querying management data and status recording information before allowing operation command execution. This preliminary validation ensures that operations meet specification requirements (such as sequential memory address usage and prior command completion) before resources are committed, preventing wasted operations and improving overall productivity despite the added monitoring step.
Solution Approach 2:
The monitoring mechanism provides real-time feedback on operation status and compliance with specifications. By using this feedback to control command execution, the system avoids executing invalid or premature operations, ensuring that each executed command is likely to succeed, thereby maintaining high working efficiency while improving reliability.
3Reliability
If status recording data is maintained for all physical units, then the operation specification compliance is improved, but the memory space consumption increases
Solution Approach 1:
The patent applies segmentation by dividing the monitoring scope into manageable units corresponding to physical units in the memory module. Status recording data is maintained separately for each physical unit, allowing the system to track operation specification compliance at a granular level. This segmentation enables efficient use of memory space by only storing status information where needed, rather than maintaining a monolithic status structure.
Data Source
AI summary
A memory operation control method, a memory storage device, and a memory control circuit unit are disclosed. The method includes the following. Management data is established, which includes status recording data. First status information corresponding to a first physical unit is stored in the status recording data. An operation command is received from a host system. The management data is queried according to the operation command. Whether to allow an execution of the operation command on the first physical unit is determined according to a query result.
