    摘要： A semiconductor integrated circuit (IC) device includes therein a test circuit. The test circuit operates to distinguish the power source level during the testing or ground level occurring at an internal node located inside the semiconductor chip. The test circuit includes a series-connected MIS transistor and an MIS diode. The gate of the MIS transistor is connected to the internal node. The MIS diode is connected to an external input/output (I/O) pin. The level at the internal node, i.e., the power source level or the ground level, can be distinguished by a first voltage level or a second voltage level applied to the external I/O pin, whichever enables a current to be drawn from the external I/O pin.

    摘要： An address buffer for a dynamic memory includes a flip-flop. The flip-flop is coupled at its one input/output terminal with both a first input circuit and a third input circuit connected in parallel with each other and at its other input/output terminal with a second input circuit. The second input circuit receives a reference voltage and is activated by an external address timing clock during a normal operation mode. The first input circuit is also activated by the external address timing clock, but receives an external address. The third input circuit receives an internal refresh address and is activated by an internal refresh address. The address buffer cooperates with a switcher which produces the internal refresh address timing clock and the external address timing clock, alternatively, by switching a basic timing clock generated by an address drive clock generator.

    摘要： A semiconductor memory device operates under a so-called address multiplex access method. A row part of the device is enabled by receiving a row address strobe (RAS) signal. A column part of the device is enabled by simultaneously receiving both a column address strobe (CAS) signal and a timing control signal supplied from the row part during its enable state. A column address buffer in the column part is enabled by simultaneously receiving both the CAS signal and a timing control signal. The timing control signal is produced from a circuit when it detects and holds the RAS signal.

    摘要： A dynamic semiconductor memory device provides a selected real cell, which is connected to a first of a pair of bit lines connected to a sense amplifier, and a dummy cell which is connected to a second of the pair of bit lines so as to perform a read-out operation. The dynamic semiconductor memory cell further provides an active restore circuit for pulling up the bit line potential of the bit line on the higher potential side of the pair of bit lines, in which the potential difference is increased by the read-out operation. The dynamic semiconductor cell can also provide a write-in circuit for charging the selected real cell through the bit line. A test power source pad is provided in the active restore circuit or the write in circuit so that when the reference level of the real cell is tested an optional power source can be applied from the test power source pad instead of from a normal power source.

    摘要： A semiconductor circuit consisting of a dynamic-type circuit and a bias-voltage generating circuit. The bias-voltage generating circuit is comprised of a first bias-voltage generator and a second bias-voltage generator. The first generator absorbs a variable substrate current, the magnitude of which is proportional to the operating frequency of the dynamic-type circuit, while the second generator absorbs a substrate current, the magnitude of which is not proportional to the operating frequency of the dynamic-type circuit. Alternately, both portions of the substrate current may be absorbed via the same circuitry.
