Abstract: A memory system comprises a controller capable of controlling a memory operation, and memory connectors capable of mounting memory modules therein, both of which are provided on a system board. Each of the memory modules has a plurality of memory chips connected to module data wirings and module power wirings respectively. The module data wirings of each memory module are connected in series form through series paths lying within the connectors. Each individual module data wirings do not constitute branch wirings to system data wirings on the system board. Thus, such signal reflection as caused by branching from the data wirings on the system board is not developed. Since the power is supplied in parallel from the system board through parallel paths lying within the connectors, the supply of the power is stabilized.

Abstract: The semiconductor IC device has a circuit arrangement constituted by a first CMOS logic gate having input and output terminals, and a second CMOS logic gate which performs the same logic operation as that of the first CMOS logic gate and which has an input terminal connected to the input terminal of the first CMOS logic gate. The arrangement also requires a differentiator circuit which has an input terminal thereof connected to an output terminal of the second CMOS logic gate and has an output terminal connected to the output terminal of the first CMOS logic gate.
