MEMORY DEVICES AND METHODS THEREOF FOR MANAGING ROW HAMMER EVENTS THEREIN - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240096391 titled 'MEMORY DEVICES AND METHODS THEREOF FOR MANAGING ROW HAMMER EVENTS THEREIN
Simplified Explanation
The memory device described in the abstract includes a row hammer managing circuit that detects a row hammer address based on a pre row hammer address and monitors a plurality of accesses to memory cells during a monitoring period. A refresh control circuit performs a refresh operation on a memory cell row physically adjacent to the row hammer address.

Unanswered Questions
How does the row hammer managing circuit detect the row hammer address accurately?
The specific mechanism or algorithm used by the circuit to detect the row hammer address is not detailed in the abstract.
What impact does the refresh operation on adjacent memory cell rows have on overall memory performance?
The abstract does not provide information on how the refresh operation affects memory access speed or latency.
Original Abstract Submitted
a memory device includes a memory cell array having a plurality of rows of memory cells therein, and a row hammer managing circuit, which is configured to detect a row hammer address based on a pre row hammer address, and each of a plurality of input row addresses associated with a plurality of accesses during a monitoring period for monitoring the plurality of accesses to a plurality of the rows of memory cells. a refresh control circuit is provided and is configured to perform a refresh operation on a memory cell row physically adjacent to a memory cell row corresponding to the row hammer address.
