    摘要: A row-related control circuit is provided which changes for a normal read operation and for refresh operation the delay time from a time at which a word line is activated to a time at which a sense amplifier is activated. Even when the refresh period is made longer and the charges in a memory cell are reduced, the sensitivity of the sense amplifier is heightened so that the refresh operation becomes possible. Thus, power consumption can be reduced by prolonging the refresh intervals.

    摘要: There is provided a test mode decision circuit which in the first WCBR cycle responds to an address key by activating a test mode entry signal and with the test mode entry signal activated in the second WCBR cycle responds to an address key by selectively activating test mode signals. In addition to a test mode signal having been activated, the test mode decision circuit further activates another test mode signal. Thus the DRAM hardly enter a test mode erroneously and is also capable of entering more than one test mode simultaneously.

    摘要: A semiconductor integrated circuit device includes an internal voltage-down converter and a voltage compensation circuit. The internal voltage-down converter provides an internal power supply voltage. The voltage compensation circuit includes a comparator, a capacitor, a transistor, and a constant current source. When the voltage (internal power supply voltage) of the output node suddenly drops, the potential at the positive input of the comparator is reduced by the coupling effect of the capacitor. As a result, the output node is charged. The potential of the positive input of the comparator is charged. As a result, the charging with respect to the output node ends.

    摘要: A P-channel MOS transistor is provided between a terminal and an SVIH detection circuit for performing test mode detection. The P-channel MOS transistor is rendered non-conductive when a potential supplied to the terminal that is used commonly for signal input during the test setting and the normal operation is a power-supply potential EXTVDD or below. The SVIH detection circuit detects that a test mode is to be set when the potential at the terminal becomes higher than a prescribed potential. During the normal operation, the terminal is disconnected from the SVIH detection circuit so that the input capacitance of the terminal can be made to be about the same as that of another input terminal, and a high speed operation becomes possible. Moreover, there is no need to take into account the parasitic capacitance of an interconnection line leading to the SVIH detection circuit.

    摘要: A refresh operation is started in response to activation of a refresh control signal. The refresh control circuit controls activation of a refresh control signal in accordance with a signal level of a row address decode enable signal in addition to signal levels of control signals activated in response to activation of signals /CAS and /RAS necessary for detecting the start of a CBR refresh operation. The row address decode enable signal is an internal control signal activated upon activation of a signal /RAS and maintained in an active state until signal /RAS is inactivated. As a result, the refresh control signal is not erroneously activated during normal operation even when a noise is caused to signal /RAS.
