ROW HAMMER CONDITION MONITORING

摘要

A system monitors data accesses to specific rows of memory to determine if a row hammer condition exists. The system can monitor accessed rows of memory to determine if the number of accesses to any of the rows exceeds a threshold associated with risk of data corruption on a row of memory physically adjacent to the row with high access. Based on the monitoring, a memory controller can determine if the number of accesses to a row exceeds the threshold, and indicate address information for the row whose access count reaches the threshold.
