  • Multi-chip modules having chip-to-chip interconnections with reduced signal voltage level and swing
    Patent number: 5461333
    Abstract: A multi-chip module is composed of two or more integrated-circuit chips located on a substrate such as a dielectrically coated silicon substrate. The chips are interconnected by means of transmission wiring lines. At least some of the chips contain one or more input buffer circuits, each composed of two branches ("legs"). Each such branch contains, in one embodiment, an n-channel MOS transistor connected in series with a pair of series-connected p-channel MOS transistors--whereby, in each such branch, one of the p-channel MOS transistors is located between (intermediate) the other of the p-channel MOS transistors and the n-channel MOS transistor of that same branch. On the other hand, in each buffer circuit, the intermediate p-channel MOS transistors of both branches are cross-coupled.
