Abstract
Counters may be provided for individual word lines of a memory for tracking word line accesses. In some examples, multiple counters may be provided for individual word lines. In some examples, the counters may be included on the word lines. The counters may be incremented responsive to word line accesses in some examples. In some examples, the counters may be incremented responsive for a time period for which a word line is held open. In some examples, the counters may be incremented responsive to both word line accesses and time periods for which the word line is held open. In some examples, count values for the counters may be written back to the counters after incrementing. In some examples, the count values may be written back prior to receiving a precharge command.
