    摘要: A MOS dynamic type RAM comprises memory cells (10), dummy cells (11), bit line pairs (BL, BL), word lines (WL), dummy word lines (DWL) and sense amplifiers (12). In a non-active cycle, the potentials of each pair of bit lines (BL, BL) are precharged at 1/2 of a supply potential V.sub.CC. Each sense amplifier (12) operates in an active cycle following the non-active cycle, while each active pull-up circuit (13) pulls up the potential of a higher level one of the pair of bit lines to V.sub.CC. This active cycle is defined by an internal RAS internal signal, which is generated by a NAND circuit (27) in response to an external RAS signal and an RPW signal obtained by delaying the external RAS signal by a delay circuit (20) and having a trailing edge obtained by delaying the trailing edge of the external RAS signal by a prescribed period.

    摘要: 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.
