TECHNIQUES FOR A MEMORY MODULE PER ROW ACTIVATE COUNTER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18401428 titled 'TECHNIQUES FOR A MEMORY MODULE PER ROW ACTIVATE COUNTER
Simplified Explanation
The abstract describes techniques for detecting and mitigating row hammer or row disturb conditions in a memory module.
- The techniques involve maintaining an activate count for a row address in a volatile memory device.
- Detection of a row hammer or row disturb condition is triggered if the activate count to the row address matches a threshold count.
- A controller for the memory module is responsible for maintaining the activate count and initiating refresh management actions to address the row hammer or row disturb condition.
Potential Applications
The technology could be applied in various computing devices that use volatile memory, such as servers, laptops, and smartphones, to prevent data corruption caused by row hammer or row disturb conditions.
Problems Solved
1. Preventing data corruption in memory modules due to row hammer or row disturb conditions. 2. Enhancing the reliability and performance of volatile memory devices.
Benefits
1. Improved data integrity and reliability in memory modules. 2. Increased lifespan of memory modules by mitigating row hammer or row disturb conditions. 3. Enhanced performance of computing devices by reducing the risk of data corruption.
Potential Commercial Applications

Possible Prior Art
There have been previous techniques developed to address row hammer issues in memory modules, such as increasing refresh rates or implementing error correction codes. However, the specific approach described in this patent application may offer a novel solution to the problem.
Unanswered Questions
How does the controller determine the threshold count for detecting a row hammer or row disturb condition?
The abstract does not provide details on how the threshold count is determined or adjusted based on the memory module's usage patterns.
What are the potential performance impacts of the refresh management actions on the memory module?
It is not clear from the abstract how the refresh management actions to mitigate row hammer or row disturb conditions may affect the overall performance of 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.
