Abstract
To provide a semiconductor memory device characterized by the fact that it can prevent errors in the redundant memory address coincidence signal generating circuit caused by the intrinsic resistance of the fuse in the fuse decoder, and it has a redundant mechanism for generating the high-speed address coincidence signal. It has multiple logic gate means and fuses programmable by the gate output. The output signal of each fuse is wired to generate address coincidence signal.
