REFRESH ROW ADDRESS

摘要

A table may include first and second row addresses that are adjacent an activated row address. A first counter of the first row address may be incremented if the activated row address is not included in the table. A second counter of the second row address may also be incremented if the activated row address is not included in the table. The first row address may be refreshed if the first counter exceeds a counter threshold. The second row address may be refreshed if the second counter exceeds the counter threshold.
