ACCESS HEATMAP GENERATION AT A MEMORY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17831270 titled 'ACCESS HEATMAP GENERATION AT A MEMORY DEVICE
Simplified Explanation
The patent application describes methods, systems, and devices for generating access heatmaps in a memory device. Here are the key points:
- The memory device maintains a register to track access operations, where each access operation of a memory address is mapped to multiple fields of the register.
- When a first access operation occurs on a first address, the memory device increments both a first field and a second field of the register.
- When a second access operation occurs on a second address, the memory device increments the first field and a third field of the register.
- The memory device also maintains a second register with fields indicating addresses where access occurrences meet a threshold.
Potential applications of this technology:
- Memory optimization: The access heatmaps can provide valuable insights into the usage patterns of memory addresses, allowing for better memory allocation and optimization.
- Performance analysis: By analyzing the access heatmaps, system designers can identify hotspots and bottlenecks in memory access, enabling them to make improvements for better performance.
- Cache management: The heatmaps can help in determining which memory addresses should be cached for faster access, improving overall system efficiency.
Problems solved by this technology:
- Lack of visibility: Traditional memory devices do not provide detailed information about access patterns, making it challenging to optimize memory usage and identify performance issues.
- Inefficient memory allocation: Without access heatmaps, memory may be allocated inefficiently, leading to wasted resources and potential performance degradation.
- Difficulty in cache management: Without insights into access patterns, it is difficult to determine which memory addresses should be cached, resulting in suboptimal cache utilization.
Benefits of this technology:
- Improved memory utilization: Access heatmaps enable better allocation of memory resources, reducing wastage and improving overall system efficiency.
- Enhanced performance: By identifying hotspots and bottlenecks, system designers can make targeted optimizations to improve memory access performance.
- Efficient cache management: With access heatmaps, cache management becomes more effective, leading to faster access times and improved system responsiveness.
Original Abstract Submitted
Methods, systems, and devices for access heatmap generation at a memory device are described. In some examples, a memory device may maintain a register for tracking access operation occurrence, for which access operations of an address of the memory device may be mapped to multiple fields of the register. In some cases, in response to a first access operation performed on a first address of the memory device, the memory device may increment a first field and a second field of the register and, in response to a second access operation performed on a second address of the memory device, the memory device may increment the first field and a third field of the register. In some examples, the memory device may maintain a second register having a set of fields that each indicate a respective address for which an access occurrence satisfies a threshold.
