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
Methods, systems, and devices for generating access heatmaps at a memory device are disclosed in this patent application. 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.
- The memory device increments specific fields of the register in response to access operations on different memory addresses.
- The register can track the occurrence of access operations and provide valuable data on the frequency of access to different memory addresses.
- The memory device also maintains a second register with fields indicating addresses that meet a certain access occurrence threshold.
- This technology enables the generation of access heatmaps, which visually represent the access patterns and frequency of different memory addresses.
- Access heatmaps can provide insights into memory usage, identify hotspots or frequently accessed areas, and help optimize memory allocation and performance.
Potential applications of this technology include:
- Memory optimization: By analyzing the access heatmaps, memory allocation can be optimized to ensure frequently accessed addresses are allocated more efficiently.
- Performance optimization: Understanding the access patterns can help identify bottlenecks and optimize memory access strategies to improve overall system performance.
- Cache management: Access heatmaps can assist in cache management by identifying frequently accessed memory addresses that can benefit from caching.
- Debugging and troubleshooting: Access heatmaps can aid in identifying memory access issues, such as excessive or inefficient access to specific addresses.
- System design and architecture: The data from access heatmaps can inform the design and architecture of memory systems, ensuring efficient and effective memory utilization.
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.
