Abstract:
Regular redundancy lines are provided dedicatedly and respectively corresponding to redundancy fuse circuits in which defect addresses are programmed. A reservation redundancy line is provided in common to the redundancy fuse circuits. Address comparison circuits each compare the defect addresses programmed in the redundancy fuse circuits with an access address and output a redundancy signal when a comparison result is a match. A switch circuit is controlled to switch according to a redundancy selection signal output from a selection fuse circuit, and validates in response to the redundancy signal either a corresponding regular redundancy line or the reservation redundancy line. By dividing the redundancy lines into the regular redundancy lines and the reservation redundancy line, each of the redundancy fuse circuits can be made to correspond to one of the plurality of redundancy lines with the simple switch circuit. Therefore, a difference in propagation delay time of a signal can be made small and a difference in access time can be made small between when relieving a defect and when there is no defect.
Abstract:
A semiconductor device having a terminal BUS being inputted with an applying voltage VBUS higher than a power supply voltage VDD, wherein a gate terminal G4 is applied with the power supply voltage VDD minus a threshold voltage Vthn when the voltage VBUS is lower than the power supply voltage VDD plus a threshold voltage Vthp and a PMOS transistor P4 is conducted. A gate terminal G2 is supplied with the power supply voltage VDD and a PMOS transistor P2 is turned off. When the voltage VBUS is equal to or higher than the power supply voltage VDD plus the threshold voltage Vthp, the PMOS transistor P4 is turned off by supplying the voltage VBUS to the gate terminal G4, while furthermore, a PMOS transistor P3 is conducted and the PMOS transistor P4 is turned off by supplying the voltage VBUS to the gate terminal G2. Unnecessary leak current is not fed from the terminal BUS regardless of the applying voltage VBUS and a correct voltage level can be sustained.
Abstract:
A transistor (11) of a driver (5) in a semiconductor integrated circuit has its gate connected to a controlling circuit (41), and has its drain connected to a sense amplifier (AMP). The controlling circuit (41)supplies the gate of the transistor (11) with a gate-to-source voltage exceeding or below other power supply voltages. The drain-to-source resistance of the transistor (11) in the on state becomes sufficiently lower as compared with that in the case of supplying the power supply voltages between the gate and source of the transistor (11). Accordingly, the amplifying speed of the sense amplifier (AMP) is heightened without altering the sense amplifier (AMP) and the driver (5). Besides, the amplifying speed of the sense amplifier (AMP) is heightened without raising the power supply voltage which supplies the carriers to the driver (5).

A prescaler that operates in a broad band. The prescaler (33) includes a buffer (41) and a counter (43). The buffer includes a first amplification circuit (50), which has three inverter circuits (52a, 52b, 52c) of different drive capacities, a second amplification circuit (54), which has four series-connected inverter circuits (54a, 54b, 54c, 54d), and a feedback circuit (55). One of the inverter circuits (52a, 52b, 52c) is connected between a capacitor (C1) and an inverter circuit (54a) via a first switch circuit (51) and a second switch circuit (53). This varies the drive capacity of the first amplification circuit (50). The feedback circuit (55) functions as a variable resistor having two transistors (T1, T2).
