The readout section is configured to read out the destructive/nondestructive states of the electrical fuse elements from the other ends of the electrical fuse elements when the read voltage is applied to the common connection node from the voltage generating section.

    摘要: The control voltage .phi.1 outputted by the control voltage generating circuit 1 is at a low level in a range where an external supply voltage Vcc is lower than the threshold value of the transistor P1, but increases continuously in analog manner when the external supply voltage Vcc rises. After having matched the external supply voltage Vcc, the control voltage .phi.1 increases in the same way as the external supply voltage Vcc. By use of the control voltage provided with the characteristics as described above for an output circuit, controlled is the gate of a transistor P4 of a low-voltage operating output section 6 operative only at a voltage lower than a predetermined value. The transistor P2 of a full-voltage operating output section 5 of the output circuit is always operative on the basis of the control signal .phi.H of the data output control circuit 3. When the external supply voltage is low below the predetermined value, the transistor P4 is perfectly turned on, so that the conductance thereof increases. In the semiconductor integrated circuit device operative on the basis of a plurality of supply voltages, it is possible to prevent the operation margin from being reduced near the switching point of the gate voltages of the driving transistors and the data output transistors.

    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.
