MEMORY DEVICE AND OPERATION METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240339145 titled 'MEMORY DEVICE AND OPERATION METHOD THEREOF
The present disclosure pertains to methods of operating a memory device with multiple rows, each containing multiple memory cells. One example method involves receiving an active command for a first row from a memory controller, reading a count from a per-row hammer tracking region of the first row, updating the count, comparing it with thresholds, outputting a target row address, and performing a row hammer mitigation operation on the corresponding row.
- Receiving active commands for specific rows from a memory controller
- Tracking counts in per-row hammer tracking regions
- Updating counts based on received commands
- Comparing updated counts with predefined thresholds
- Outputting target row addresses based on the comparison results
- Performing row hammer mitigation operations on identified rows
Potential Applications: - Memory devices in computers - Data centers - Mobile devices
Problems Solved: - Preventing row hammer issues in memory devices - Enhancing memory device reliability and longevity
Benefits: - Improved memory device performance - Reduced risk of data corruption - Enhanced system stability
Commercial Applications: Title: Memory Device Row Hammer Mitigation Technology This technology can be used in various commercial applications such as: - Computer hardware manufacturing - Data center management - Mobile device production
Questions about Memory Device Row Hammer Mitigation Technology: 1. How does this technology improve memory device reliability? - This technology helps prevent row hammer issues, which can lead to data corruption and system instability. 2. What are the potential implications of using this technology in data centers? - Implementing this technology in data centers can enhance overall system performance and reduce the risk of memory-related failures.
Original Abstract Submitted
the present disclosure relates to operation methods of a memory device including multiple rows each including multiple memory cells. one example method includes receiving an active command for a first row from a memory controller, reading a first count from a per-row hammer tracking (prht) region of the first row, updating the first count to generate a first updated count, comparing the first updated count with one of first and second thresholds to generate a comparison result, wherein when the first row is adjacent to the given row, the first updated count is compared with the first threshold and when the first row is not adjacent to the given row, the first updated count is compared with the second threshold, outputting a target row address based on the comparison result, and performing a row hammer mitigation operation on a row corresponding to the target row address.
