DEVICE, OPERATING METHOD, MEMORY DEVICE, AND CXL MEMORY EXPANSION DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18470471 titled 'DEVICE, OPERATING METHOD, MEMORY DEVICE, AND CXL MEMORY EXPANSION DEVICE
Simplified Explanation
The abstract describes a device and method for managing a row hammer attack in memory systems. The device includes a memory controller that detects row hammer attack patterns and determines whether to perform refresh management based on the type of row distribution.
- Memory controller detects row hammer attack patterns and row distribution of addresses.
- Determines whether to perform refresh management based on row distribution type.
- Provides refresh management commands and target row addresses to volatile memory for every access corresponding to the attack pattern size.
Potential Applications
This technology could be applied in various memory systems, such as servers, data centers, and high-performance computing environments, to prevent row hammer attacks and ensure data integrity.
Problems Solved
This technology addresses the issue of row hammer attacks, which can cause data corruption and system instability in memory devices. By detecting and managing these attacks, the technology helps maintain the reliability and performance of memory systems.
Benefits
- Improved data integrity and system stability. - Enhanced security against row hammer attacks. - Optimal performance of memory systems.
Potential Commercial Applications
- Server and data center memory systems. - High-performance computing environments. - Cloud computing infrastructure.
Possible Prior Art
One prior art in this field is the use of error-correcting codes (ECC) in memory systems to detect and correct data errors caused by various factors, including row hammer attacks. ECC has been widely used to enhance data reliability in memory devices.
What is the impact of this technology on memory system performance?
This technology significantly improves memory system performance by effectively managing row hammer attacks, ensuring data integrity, and preventing system instability.
How does this technology compare to existing solutions for preventing row hammer attacks?
Compared to existing solutions like ECC, this technology provides a more proactive approach to detecting and managing row hammer attacks, thereby offering enhanced security and reliability for memory systems.
Original Abstract Submitted
A device, an operating method of a memory controller, a memory device, and a compute express link (CXL) memory expansion device all for managing a row hammer are provided. The device includes a volatile memory and a memory controller that is configured to detect, based on input row addresses, a pattern size of a row hammer attack pattern and a row distribution of row hammer addresses, to determine, according to a type of the row distribution, whether to perform refresh management, and for every L access corresponding to the pattern size, to provide, to the volatile memory, a refresh management command and a target row address, where L is an integer greater than or equal to 1.
