TECHNIQUES FOR A MEMORY MODULE PER ROW ACTIVATE COUNTER - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240134982 titled 'TECHNIQUES FOR A MEMORY MODULE PER ROW ACTIVATE COUNTER
Simplified Explanation
The abstract of the patent application describes techniques for detecting and mitigating row hammer or row disturb conditions in a memory module by monitoring the activate count to a specific row address.
- The techniques involve maintaining an activate count for each row address in the memory module.
- If the activate count to a row address matches a threshold count, a row hammer or row disturb condition is detected.
- Detection of the condition can trigger refresh management actions to mitigate the issue.
- The activate count is controlled by a controller for the memory module.
Potential Applications
The technology described in this patent application could be applied in various fields where memory modules are used, such as:
- Computer systems
- Mobile devices
- Servers
Problems Solved
The technology addresses the following problems:
- Row hammer and row disturb conditions in memory modules
- Data corruption due to these conditions
- Performance degradation in memory systems
Benefits
The benefits of this technology include:
- Improved reliability of memory modules
- Enhanced performance of memory systems
- Prevention of data loss or corruption
Potential Commercial Applications
The technology could be commercially applied in industries such as:
- Electronics manufacturing
- Data centers
- Telecommunications
Possible Prior Art
One example of prior art related to this technology is the use of error-correcting codes (ECC) in memory systems to detect and correct data errors. ECC is commonly used in memory modules to ensure data integrity.
=== What are the specific techniques used to detect row hammer or row disturb conditions in memory modules? The specific techniques involve monitoring the activate count to a row address and comparing it to a threshold count to detect the conditions.
=== How do the refresh management actions help mitigate row hammer or row disturb conditions in memory modules? The refresh management actions triggered by the detection of these conditions help prevent data corruption and performance degradation by refreshing the affected rows in the memory module.
Original Abstract Submitted
examples include techniques for a memory module per row activate counter. the techniques include detecting a row hammer or row disturb condition for a row address at a volatile memory device if an activate count to the row address matches a threshold count. the activate count is maintained by a controller for the memory module. detection of the row hammer or row disturb condition can cause refresh management actions to mitigate the row hammer or row disturb condition.
