ROW TRACKING FOR ROW HAMMER MITIGATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18237786 titled 'ROW TRACKING FOR ROW HAMMER MITIGATION
Simplified Explanation
The abstract describes a control mechanism implemented in the back-end of a memory sub-system to refresh rows of a memory device based on the number of times the rows have been updated in a duration of time. The mechanism also considers the time between the activation command and pre-charge command for a row, and utilizes a pair of counters to retain data between different consecutive durations of time.
- Rows of a memory device are refreshed based on the number of times they have been updated in a specific time period.
- Rows are also updated based on the time between receiving an activation command and a pre-charge command for the row.
- A pair of counters are used to implement a ping pong mechanism to retain data between different consecutive durations of time.
Potential Applications: - Memory devices in computers and other electronic devices - Data storage systems - Embedded systems
Problems Solved: - Ensures that memory rows are refreshed appropriately to maintain data integrity - Optimizes memory performance by updating rows efficiently
Benefits: - Improved reliability of memory devices - Enhanced performance of memory sub-systems - Efficient data retention and management
Original Abstract Submitted
A control mechanism may be implemented in a back-end of a memory sub-system to refresh rows of a memory device. Rows of the memory device can be refreshed based on a quantity of times the rows have been updated in a duration of time. Rows of the memory device can also be updated based on a duration of time between receipt of the activation command for the row and a pre-charge command for the row. Row of the memory device clan further be updated utilizing a pair of counters that implement a ping pong mechanism to retain data between different consecutive durations of time.
