Abstract
The address of victim rows may be determined based on rows that are accessed in a memory. The victim addresses may be stored and associated with a count for every time a victim row is 'victimized.' When the count for a victim row reaches a threshold, the victim row may be refreshed to preserve data stored in the row. After the victim row has been refreshed, the count may be reset. When a victim row is accessed, the count may also be reset. The counts may be adjusted for closer victim rows (e.g., +/−1) at a faster rate than counts for more distant victim rows (e.g., +/−2). This may cause closer victim rows to be refreshed at a higher rate than more distant victim rows.
