    Abstract: In a DRAM of separated I/O type, column selecting lines for reading data and column selecting lines for writing data are provided independently from each other. An addition circuit is provided corresponding to each memory cell array block for precharging, when that memory cell array is not selected, a read line pair corresponding that memory cell array block to the same potential Vb1 as that of the bit lines equalized by an equalizer circuit. Both in data reading and writing operations, current does not flow between any equalizer circuit and the write data line pair provided corresponding to each unselected memory cell array block in spite of the fact that a transistor for write selection is not provided in each bit line pair.

    Abstract: There is disclosed a dynamic random access memory device of the type capable of periodic self-refresh cycles of operation. The DRAM includes the detector circuit for detecting the designation of the self-refresh mode and a voltage generator circuit for generating a voltage to precharge the bit line pair. During the self-controlled refresh cycle, the bit line pair is equalized and precharged to a voltage lower than Vcc/2. When it is attempted to set the time interval between the self-refresh cycles in order to reduce current consumption, the level of voltage stored in the memory cell capacitor tends to decrease due to charge leakage. However, it is implemented to provide and keep a potential difference between the precharge voltage on the bit line pair and the voltage stored in the capacitor thereby to secure the desired sensing margin for the sense amplifier.

    Abstract: 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.
