ABSTRACT:
In the present invention, a precharge circuit includes a precharge supply for setting equal potentials at pairs of spaced signal lines extending in parallel with respect to each other, a pair of switching elements for connecting and disconnecting respective signal lines to the supply, and a short circuit switching element for connecting and disconnecting short circuiting of the signal lines. The short circuit switching element consists of a transistor comprising a source and drain constituted by a pair of impurity regions formed underneath the pair of signal lines so as to correspond to the pair of signal lines and a gate. The gate of the transistor is formed in such a manner that gate length coincides with the widthwise direction of the pair of signal lines.
