Abstract
A redundant multiplexer, in which the addresses of two series-connected switches are compared, and the switches are possibly interchanged, to ensure that no faulty bit lines are read. The redundant multiplexer is used in a semiconductor memory configuration having redundant bit lines for replacing faulty bit lines. The redundant bit line received control and switching signals to determine which of the bit lines are to be replaced.
