Latest Patents
One of Minamimura's latest patents is the Bi-MOS PLA, which describes an integrated programmable logic array formed within a single silicon chip. This innovative design combines a logical product gate array and a logical summation gate array. The logical product gate array utilizes multiple MIS field-effect transistors, whose gates are selectively driven by various input signals, with their source-drain paths connected in series. The logical summation gate array features a plurality of inverted bipolar transistors, with collector-emitter paths connected in parallel.
Another significant patent is for a logic circuit that operates on a large scale while consuming minimal electric power. This circuit comprises several ROM portions formed of IIL circuits. Input signal lines are used to transmit signals to these ROM portions, which are selectively activated by ROM select signals. The design allows for a logic circuit that consumes little power due to the non-selected ROM portions remaining in a floating condition, thus not consuming any power.
