    摘要: A semiconductor memory device of a synchronous type is disclosed, which has an output control circuit (14) adapted to output signals D2T and D2N by activating one of two conduction control signals D1T or by inactivating both of the conduction control signals in accordance with an output control signal MSK2B or OEB for controlling whether a data output terminal DQ is to be actuated or set into a high impedance, and an output circuit 17 provided with a couple of latch circuits 15 and 16 each adapted to individually latch and output the corresponding conduction control signals in synchronism with an internal synchronizing signal .phi.3. There is further provided an additional latch circuit 13 latching the output control signal in response to an inverted signal of the internal synchronizing signal .phi.3.

    摘要: A semiconductor memory device has a voltage converter for converting a voltage level of an internal clock signal to obtain a high voltage level clock signal. The high level clock signal accelerates the transmission of the clock signal to latch circuits which control the output transistors of the memory device. Another voltage converter is disposed between the data amplifier and the latch circuit instead of the output of the latch circuit, for prevention of current flowing through both the output transistors.
