    摘要: A semiconductor memory device including a memory cell array, bit lines, and sense amplifier groups. The memory cell array is composed of a plurality of memory cells arranged roughly in a matrix pattern. A plurality of the memory cells arranged in a row are activated in response to a row address decode signal. A pair of the bit lines are provided for each column. The data of the corresponding activated memory cells are transmitted to the bit line pair. Each of the sense amplifier groups has n-units of sense amplifiers each connected to the bit line pair, to sense and amplify data read to the bit line pair connected thereto. The respective reference potential terminals of the sense amplifiers of each of the sense amplifier groups are connected to a single common node which can be connected to a reference potential via a sense amplifier activating transistor turned on in response to a row address signal. The sense amplifiers can be operated at high speed, while preventing erroneous operation, because the wiring resistances and the parasitic capacitances of the common source node of the sense amplifiers can be reduced.

    摘要: A semiconductor integrated circuit includes memory cell blocks having memory cells arranged in matrix, sense amplifiers, each located adjacent to the memory cells, and sense amplifier control circuits, each of the sense amplifier control circuit being located on outside of the memory cell block. The sense amplifier control circuit has a standard voltage generating circuit and a control circuit for receiving the standard voltage and for transferring a driver signal to the sense amplifier to control the charging ability of the sense amplifier. The source voltage has three voltage regions, first, intermediate, and second regions. In the first voltage region, the potential of the driver signal increases with the increase of the source voltage. In the intermediate voltage region (2.7 to 3 Volt), the potential of the driver signal is changed oppose to the change of the source voltage, and in the second voltage region, the potential of the driver signal decreases with the increase of the source voltage.

    摘要: In a semiconductor memory device having plural pairs of bit lines and plural sense amplifiers, a gate electrode of a sense amplifier transistor for sensing potential of a first side of a first bit line pair is formed with an extension portion extending under and along the first side of a second bit line pair. A capacitance C.sub.B formed between the extension of the gate electrode and the first side of the second bit line pair is determined to be equal or larger than capacitance C.sub.A formed between the first side of the first bit line pair and the gate electrode. Since the potential of the first side of the bit line pair fluctuates roughly in phase with that of the second side of the same bit line pair, a harmful influence due to interference noise can be reduced, without increasing the chip layout area, by only modifying the shapes of the gate electrodes of the sense amplifier transistors.

    摘要: The semiconductor device comprises: an internal supply voltage deboosting circuit for inputting an external supply voltage, deboosting the inputted external supply voltage, and outputting a deboosted voltage as an internal supply voltage; a first control circuit for deactivating the internal supply voltage deboosting circuit when the external supply voltage is lower than a predetermined value; and a second control circuit for outputting the external supply voltage as the internal supply voltage when the external supply voltage is lower than the predetermined value. When the external supply voltage is lower than a predetermined value, since the internal supply voltage deboosting circuit is deactivated by the first control circuit, the current consumption can be reduced. Further, since the external supply voltage is outputted as the internal supply voltage by the second control circuit, the deboosting operation is not required. The device is usable for different external supply voltages in spite of the same circuit configuration, while preventing the operational margin from being deteriorated.
