ABSTRACT:
The potential of a data line is precharged to an H level by a P channel MOS transistor rendered conductive by a precharge signal. The potential of the data line is not driven by a differential amplifier circuit until the difference between the potential of the output of the differential amplifier circuit providing a corresponding signal and the potential (H level) of the data line become the level of a threshold voltage Vth(n) of an N channel MOS transistor. Therefore, erroneous data will not be provided to the data line even in the case of insufficient equalization of an I/O line pair or when there is an offset in the differential amplifier circuit.
