Abstract
A dynamic random access memory includes a dummy word line which has an electrical characteristic identical to that of an actual word line. The dummy word line is charged up and is then discharged as in case of the actual word line. A latched row address in a row address latch circuit is reset when the potential of the dummy word line becomes equal to a predetermined low potential due to the discharge operation for the dummy word line.
