DIRECTED REFRESH MANAGEMENT FOR DRAM - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240112722 titled 'DIRECTED REFRESH MANAGEMENT FOR DRAM
Simplified Explanation
The abstract describes a memory controller that includes a row hammer logic circuit to generate accesses for a memory. It provides a sample request to the memory, generates a sample command for the memory to capture a current row, and then sends a mitigation command after the sample command is completed.
- Memory controller with row hammer logic circuit
- Sample request triggers sample command for memory access
- Mitigation command sent after sample command completion
Potential Applications
The technology could be applied in various memory systems where row hammering may be a concern, such as in high-performance computing, data centers, and gaming consoles.
Problems Solved
1. Preventing row hammering in memory systems 2. Improving memory access efficiency and reliability
Benefits
1. Enhanced memory performance 2. Reduced risk of data corruption due to row hammering 3. Increased system stability and longevity
Potential Commercial Applications
Optimizing memory performance in servers, improving gaming experience in consoles, and enhancing data processing in high-performance computing systems.
Possible Prior Art
One possible prior art could be memory controllers with row hammer mitigation techniques implemented in hardware or software to address similar issues.
Unanswered Questions
How does the row hammer logic circuit determine when to send the mitigation command?
The abstract does not provide details on the specific criteria or algorithm used by the row hammer logic circuit to decide when to trigger the mitigation command.
What impact does the mitigation command have on memory performance and latency?
The abstract does not mention the potential effects of the mitigation command on memory access speed or overall system performance.
Original Abstract Submitted
a memory controller for generating accesses for a memory includes a row hammer logic circuit for providing a sample request. in response to the sample request, the memory controller generates a sample command for dispatch to the memory to cause the memory to capture a current row. in response to a completion of the sample command, the memory controller generates a mitigation command for dispatch to the memory.
