    摘要: A semiconductor device having the function of generating an internal clock signal delayed by a predetermined phase by adjusting the phase of an external clock signal, includes a first clock phase circuit for roughly adjusting the phase of the external clock signal; and a second clock phase adjusting circuit for controlling the phase of the internal clock signal with higher accuracy than the first clock phase adjusting circuit. The semiconductor device having such a construction executes phase comparisons by the first and second clock phase adjusting circuits independently of each other, and when a phase control operation by the second clock phase adjusting circuit is made subordinate to that of the first clock phase adjusting circuit, the delay time of each of a plurality of delay elements inside the first clock phase adjusting circuit is set to a value larger than a power source jitter resulting from a noise of a power source and a jitter of the external clock signal.

    摘要: The present invention relates to a memory device including memory cells each formed of a cell transistor connected to bit and word line and a cell capacitor. The memory device includes a pre-charging circuit for pre-charging bit line to a first voltage, a sense amplifier for detecting voltages of bit lines and driving the bit lines to a second voltage for H level or a third voltage for L level, and a word line driving circuit for driving word lines to make the writing voltage for H level of the cell capacitor to a fourth voltage lower than the second voltage. The present invention is characterized in that the first voltage is lower than an intermediate value between the second and third voltages. According to the present invention, it becomes possible to prevent the voltage V.sub.ds of the cell transistor from being zero by setting the writing voltage (fourth voltage) for H level of the cell capacitor to be lower than the voltage for H level (second voltage) of the bit line, thus reducing a time of writing or re-writing data. Additionally, a pre-charge voltage (first voltage) of the bit lines is set to be lower than the half of the amplitude of the bit line. Thereby, it also becomes possible to prevent the very small voltage of the bit line from being smaller according to the lowered H level voltage in the memory cell.

    摘要: A semiconductor integrated circuit producing a given output voltage includes first and second operational amplifiers, and first and second transistors. The first and second operational amplifiers detect a voltage difference between a voltage applied to an input terminal and at least one reference voltage. The first and second transistors are turned ON or turned OFF according to the levels of voltages output from the first and second operational amplifiers. The first operational amplifier receives the output voltage at the input terminal. When the level of the output voltage becomes lower than the reference voltage, the first operational amplifier allows the first transistor to operate so as to raise the output voltage. In contrast, the second operational amplifier receives the output voltage at the input terminal. When the level of the output voltage exceeds the reference voltage, the second operational amplifier allows the second transistor to operate so as to lower the output voltage.
