摘要： A memory device having a memory element including a plurality of memory cells each designated by a row address signal and a column address signal, and a circuit for detecting a transition between the row address signal and the column address signal to thereby effect an equalize operation on the memory element. The supply of a row/column address signal including the row address signal and the column address signal to the memory element is cut off during a logical indeterminate period at the time of the transition. The row/column address signal immediately before its cutoff is held and the held signal is supplied to the memory element during the logical indeterminate period. Thus, a high-speed operation can be done by the equalize operation and the cutoff can provide the prevention of occurrence of a malfunction due to noise such as a glitch or the like.

摘要： A noise elimination method is characterized in that when transmitting signals in the same direction on at least two distributed constant lines, a resistance of a terminating resistor at a far-end is set so that voltages propagated to the far-end become equal between two kinds of propagation modes on coupled distributed constant lines. The two kinds of propagation modes are a common mode which propagates with respect to a ground plane and a differential mode which propagates between the coupled lines.

摘要： A constant current circuit having an output current I.sub.2 which changes with the change of the power source voltage V.sub.cc, and an oscillating circuit whose oscillation frequency is made variable by the change of I.sub.2 in the constant current circuit. The constant current circuit comprises bipolar transistors coupled to form a differential amplifier, wherein one of the transistors is supplied with a reference voltage and another is supplied with a divided voltage of V.sub.cc, and a resistor connecting the emitters of the transistors is provided for controlling the slope of the V.sub.cc -I.sub.2 characteristic curve of the constant current circuit. The oscillating circuit comprises a capacitor charged with I.sub.2 and a switching circuit for discharging the capacitor when it is closed and a voltage detecting circuit operating to close or open the switching circuit according to the detection of the voltage at an end of the capacitor. Thus, the switching circuit operates on and off to generate pulses with frequency depending on I.sub.2, hence, depending on V.sub.cc. Methods for controlling the frequency range of the oscillating circuit and the rise time to fall time ratio of the pulses by introducing additional constant current supplying sources are also disclosed.
