Abstract
A dummy word line driving circuit for a MOS dynamic RAM comprises a dummy word line controller connected to each end of a pair of dummy word lines. A sub-decode signal which is opposite to the one inputted to a dummy word driver and a dummy set signal for writing a bit line information into a not-selected dummy cell are inputted to the dummy word line controller. Means for applying a dummy equalizing signal is connected to two full-sized dummy cells, for equalizing the two before the dummy word line is driven. The two full-sized dummy cells are equalized by the signal, resulting in a charge amount, which is to be a reference value, of a half of a full-sized memory cell.
