    摘要: Signals outputted from an I/O buffer with a parallel drive configuration are stabilized for reliability enhancement. Each I/O cell has a complementary I/O cell that outputs one output signal as a complementary signal made up of a non-inverted signal and an inverted signal. Two I/O cells are coupled in parallel. Output portions of first inverters are coupled together through a first wiring; and output portions of second inverters are coupled together through a second wiring. The first wiring is formed on the lower side of the I/O cells so that it is astride the two I/O cells, and the second wiring is formed above the first wiring so that it is astride the two I/O cells. The wirings are laid out so that the wiring length of the first wiring and the wiring length of the second wiring are substantially equal to each other.

    摘要: A semiconductor device having amplifying circuits provided near corresponding bonding pads receiving external signals, and positioned between the bonding pads and internal circuits to which such external signals are to be applied. The device includes a control signal generating circuit for the amplifying circuits which is not provided in conventional semiconductor devices. In response to external control signals, the control signal generating circuit generates internal control signals for controlling electric paths between a power supply and ground in the amplifying circuits. During the standby period of the semiconductor device, the paths between the power supply and ground are cut regardless of the potential of the corresponding bonding pads, preventing flow of a through current.

    摘要: A semiconductor integrated circuit device in which circuit functions can be remedied or changed by severing at least a portion of a circuit pattern and a method for producing such semiconductor integrated circuit device. The circuit pattern is formed on the semiconductor substrate. A field shield plate is formed on the major surface of the semiconductor substrate for electrically separating respective elements constituting the circuit. The circuit pattern includes a fuse element. The fuse element is provided on the field shield plate. The portion of the field shield plate lying directly below the fuse element is isolated from other portions of the field shield plate. In such semiconductor integrated circuit device, the portion of the field shield plate lying directly below the fuse element is separated from other portions of the field shield plate, so that short-circuiting between the semiconductor substrate and the field shield plate cannot occur even when the laser beam is irradiated with a laser beam deviation at the time of severing of the fuse element.

    摘要: Internal read out data bits are divided into a plurality of data groups, and data bits in corresponding positions in different data groups are paired off. A determination gate is provided to each pair of data bits, and determining operation is performed in each pair to compress the result of determination to finally generate a 1-bit flag indicating a match/mismatch in logic level among the internal read out data. Consequently, a multi-bit test circuit that has a reduced layout area and can perform high-speed multi-bit determination is provided.
