A semiconductor device facilitates keeping all parasitic resistance values between contact portion of a common source (V.sub.cc) line and intrinsic collector operation regions of respective transistors small enough so as not to exceed predetermined values and so as to be nearly identical. The parasitic resistance values are made small and nearly identical by disposing collector electrode connecting layers between base impurity introducing layers of respective transistors provided with predetermined intervals in a semiconductor substrate. Because of this arrangement to minimize and equalize resistances, the voltage drops generated by the parasitic resistances applied to respective transistors are suppressed so as to be lower than or not substantially exceed the operation threshold voltages of the parasitic transistors.

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.

摘要:
In a multi-rank memory module having a terminal resistance of a data input/output pad 13 and a terminal resistance control pad 14 that inputs a signal that controls on/off of the terminal resistance, a high-speed operation is enabled with the aid of an enclosed terminal resistance, even in cases where the number of ranks is greater than that of terminal resistance control terminals (ODT terminals) provided on the memory module. To this end, a terminal resistance control pad 14 of a memory chip 12, having a longer length of an interconnect between a data bus 19 on a module substrate 8 and a data input/output pad 13, is connected to a terminal resistance control interconnect 18 or 21 to control the on/off of the terminal resistance from the ODT terminal. A terminal resistance control pad on a memory chip 11, having a shorter length of an interconnect between the data bus 19 on the module substrate and the data input/output pad 13, is connected to a fixed potential 20 to turn on the terminal resistance.

A memory module includes a memory chip MC1 disposed at a position opposite to a memory buffer via a module substrate, a memory chip MC3 disposed at a position not opposite to the memory buffer via the module substrate, and a memory chip MC11 disposed at a position opposite to the memory chip MC3 via the module substrate. A branch point at which a wiring part connected to the memory chip MC1 and a wiring part connected to the memory chips MC3 and MC11 are branched is positioned at the memory buffer side from the viewpoint of the intermediate point between the planar mounting position of the memory buffer and the planar mounting position of the memory chips MC3 and MC11. Accordingly, the wiring length of the wiring part can be made sufficiently short.
