    摘要： A semiconductor integrated logic circuit is provided which includes a plurality of logic gates each having a first input terminal for respectively receiving first input signals, wherein each of the logic gates is coupled to a common node. In one embodiment, first and second switching elements are also coupled to the common node. The first and second switching elements are both coupled to a second input terminal for receiving a second input signal which is common to the plurality of logic gates, and both operate complementary to one another in response to the second input signal. This arrangement is particularly effective for decoders in semiconductor memory circuits which use a common NMOS to receive one input for a plurality of logic decoder gates. An improved read/write arrangement is also provided for semiconductor memory circuits which includes circuitry to prevent connection of a common read line to the data lines during the writing operation. This enhances the writing speed by removing the load of the common read line during writing.

    摘要： An invention is disclosed, which is suitable for operating a bipolar-MOS logic circuit, and in particular Bi-CMOS logic circuit with a low power supply voltage below 5V, e.g. around 3V. According to the present logic circuit, since the base current of a second NPN transistor is supplied from a power supply through a PMOS transistor (first current switching means), the impedance of which is lowered previously by a logic inverting means and an NMOS logic circuit (second current switching means), which is on/off controlled by an input signal, in a transient logic level transition period where the output is switched from the level "1" to "0" (i.e. it falls), it is possible to supply a sufficient base current to the second NPN. In this way, it is possible to turn-on the second NPN with a high speed and to pull down to the level "0" with high speed. Further, since the PMOS is switched off owing to the action of the logic inverting means just after having allowed a sufficient base current flow therethrough, the current path, through which the base current of the second NPN is supplied, is stopped and thus DC power consumption is elimated.

    摘要： A plurality of memory cells are tested in order. Each time a defective memory cell is detected by the test, error pattern information is updated based on a relative arrangement relationship between a plurality of defective memory cells, and error address information is updated based on the addresses of at least part of the plurality of defective memory cells. According to the present invention, it is possible to significantly reduce the storage capacity of the analysis memory. This allows the implementation of the analysis memory itself in the semiconductor device, in which case external testers need not include the analysis memory.
