    摘要： A memory module includes a plurality of memory chips and a plurality of data register buffers mounted on the module substrate. At least two memory chips are allocated to each of the data register buffers. Each of the data register buffers includes M input/output terminals (M is a positive integer equal to or larger than 1) that are connected to the data connectors via a first data line and N input/output terminals (N is a positive integer equal to or larger than 2M) that are connected to corresponding memory chips via second and third data lines, so that the number of the second and third data lines is N/M times the number of the first data lines. According to the present invention, because the load capacities of the second and third data lines are reduced by a considerable amount, it is possible to realize a considerably high data transfer rate.

The circuit includes a current generating section that generates a first current having a positive temperature coefficient, a voltage generating section that generates a voltage having a negative temperature coefficient, a synthesis section that generates a voltage which is the sum of a voltage having a positive temperature coefficient and developed across both terminals of a resistor, where the voltage has a negative temperature coefficient, and a compensation current generating section that generates a second current having a positive temperature coefficient. The current corresponding to the sum of said first and second currents is caused to flow through the resistor. The synthesis section generates a voltage which is a sum of a terminal voltage of the resistor by the sum current of the first and second currents and the voltage having a negative temperature coefficient.

    摘要： Disclosed is a reference voltage generating circuit which includes resistors R0, R0 and R3, a differential amplifier A1 and transistors Q1, Q2 and Q3. The collectors of the transistors Q1 and Q2 are connected to differential input terminals of the differential amplifier, while one ends of the R0, R0 and R3 are connected in common to an output of the differential amplifier A1. The other ends of the two resistors R0 are connected in common to the collectors of the transistors Q1 and Q2, while the other end of the resistor R1 is connected to the collector and the base of the transistor Q3, which transistor Q3 has the base connected to the bases of the transistors Q1 and Q2. The emitter size ratio of the transistors Q1 and Q2 is set to 1:N. A current of a value approximately equal to that of the collector current of the transistor Q1 or Q2 and a current with a positive temperature coefficient larger than the first-stated current are caused to flow through the resistor R1. The reference voltage generating circuit outputs a voltage corresponding to the sum of a voltage generated across both ends of the resistor R1 and a base-to-emitter voltage VBE3 of the transistor Q3.
