Abstract
A redundancy row decoder in a DRAM includes a plurality of N channel MOS transistors connected in series between one terminal of each fuse and a line of a ground potential, the plurality of N channel MOS transistors having their gates receiving a predecode signal allocated to a corresponding word line. As compared with a conventional case where only one N channel MOS transistor is connected between one terminal of each fuse and the line of the ground potential, leakage current flowing through each fuse is made smaller.
