摘要： Column repairing circuits 7a, 7b for repairing a DRAM in which there are defective memory cells in two columns are disclosed. The connection state of switching elements or circuits 51-5n, 61-6n, 71-7 (n+1), 81-8 (n+1) is determined as illustrated by appropriately disconnecting fuses in fuse links provided respectively in circuits 7a, 7b. Accordingly, column selecting lines Y2a and Y (n+1) b in memory array blocks 891a, 891b are not activated. The two repairing circuits 7a, 7b are provided spaced apart from each other on a semiconductor substrate, so that excessive concentration of fuse elements and switching elements or circuits is prevented.

摘要： A clock generator circuit of a dynamic RAM comprises a power-on reset circuit and an NOR gate connected to a RAS terminal and the reset circuit. In operation, the powre-on reset circuit generates a one-shot pulse immediately after the power supply is turned on. During a period of a pulse width of the one-shot pulse, this clock generator circuit operates as if it receives a high-level RAS signal and, as a result, it is possible to reduce an excessive current flowing into the dynamic RAM at the time of turning on the power supply.

摘要： A delay circuit having a complementary insulated gate device comprises an inverter (10) having a series connection of a p type field effect transistor Q3 and an n type field effect transistor Q4 and a transmission gate (20) having a parallel connection of a p type field effect transistor Q1 and an n type field effect transistor Q2 connected to the preceding stage of the inverter (10), and the gates of the transistors Q1 and Q2 are connected together to an output terminal (3). The logical threshold voltage of the inverter (10) is set at a higher value in the range of the input voltage of the inverter (10). There is a peculiar period in which the transistors Q1 and Q2 of the transmission gate (20) transmit only a little increase of the input voltage to the inverter (10) during the increase of the input voltage. Due to the existence of this peculiar period, this circuit outputs a delayed output signal only when the input voltage increases. In addition, the rise time and fall time of the output signal are short.

摘要： A resistor is connected to an input portion of a CMOS inverter. An input of the CMOS inverter is affected by a time constant of an RC circuit comprising the resistor and gate stray capacitance of the CMOS inverter. In addition, there is provided an n channel MOS transistor having a drain and a source connected to both ends of the resistor, respectively, and a gate connected to an input signal source. Only in the rising portion of an input signal, the n channel MOS transistor is turned on, so that the resistor is bypassed. Thus, a waveform of output of the CMOS inverter is not delayed at the falling portion. Only at the rising portion, the waveform thereof is delayed due to the time constant of the above described RC circuit.

摘要： A substrate bias circuit controls application of a conventional substrate charge pump to the substrate of a semiconductor integrated circuit to prevent latching up of parasitic transistors at the time of turn on of power to the integrated circuit. The substrate bias circuit comprises a filed effect transistor having its source and drain electrodes connected between substrate and charge pump. The gate electrode of the transistor is driven through an RC circuit by the power supply to turn on the transistor for a predetermined time period at the time power is initially applied to the integrated circuit. There is no latching up of the parasitic transistors because application of positive bias voltage to the substrate during turn-on is prevented.

摘要： An input circuit of a semiconductor device includes a P type well formed on the main surface of a semiconductor substrate, and an N type region formed on the main surface in the P type well. A P-N junction is formed by the N type region and the P type well. An input voltage is applied to the N type region, which input voltage is applied to an internal circuit formed on the semiconductor substrate. When the P-N junction is rendered conductive by an application of an excessive voltage to the input voltage, the current caused by the excessive voltage is absorbed to the supply potential through the P type region formed in the P well.
