Memory Row-Copy Error Control Using Column Address Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing memory management operations, such as row-copy and sense-copy operations, often fail to incorporate error control, leading to the propagation and introduction of errors during data transfer, which undermines the effectiveness of wear-leveling and other distribution strategies.
Innovation Solution
Implementing error control operations in memory management operations, including row-copy and sense-copy, by using a column address counter to track and correct errors, ensuring each memory cell is properly copied and stored, thereby preventing error propagation and introducing error correction mechanisms during data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If error control operations are not implemented in memory management operations, then the device complexity remains low, but errors propagate and reliability deteriorates
Solution Approach 1:
The memory device performs self-diagnosis and self-correction by monitoring its own operational status through status indicators and automatically executing compensation operations when errors are detected, eliminating the need for external error control mechanisms
Solution Approach 2:
The system uses status indicators to monitor memory cell states and provides feedback to trigger compensation operations, creating a closed-loop error control mechanism that automatically responds to detected errors
2Reliability
If error control operations are implemented in every memory management operation, then reliability improves, but the productivity decreases due to additional processing steps
Solution Approach 1:
Error control operations are applied selectively based on detected needs rather than universally to all operations, using status indicators to determine when compensation operations are necessary, thus avoiding unnecessary processing overhead
3Ease of operation
If wear-leveling operations are performed without error control, then the ease of operation is maintained, but harmful factors increase due to error propagation
Solution Approach 1:
The memory device automatically detects and corrects errors during wear-leveling operations through self-monitoring mechanisms, maintaining operational simplicity while eliminating error propagation through autonomous error control

AI summary
Methods, systems, and devices for error control for memory device are described. A memory device may be configured to perform memory management operations including error control operations. For example, a memory device may be configured to perform an error control operation on data stored in a first memory cell coupled with a source row of a memory array. The memory device may be configured to write the data to a second memory cell coupled with the target row of the memory array based on performing the error control operation on the data and determine whether the management operation is complete based at least in part on the first column address of the first memory cell. The memory device may also generate an output signal to perform the error control operation on a third memory cell coupled with the source row based on determining whether the management operation is complete.
