Abstract
In a semiconductor memory device a column decoder outputs column select signals which are in turn transmitted to a memory cell block via a transfer gate which turns on when a signal fed through a WBI pad is placed in the inactive state. Even-numbered column select lines are connected via a transfer gate to an even-numbered CSL pad, and odd-numbered column select lines are connected via the transfer gate to an odd-numbered CSL pad.
