Abstract

A redundancy fuse box of a semiconductor memory device which minimizes address line loading by organizing fuse cells into fuse cell groups sharing the same sub-address line. The address signal therefore has to traverse across a shorter distance along the semiconductor device, which contributes to a reduction in cell line loading. The redundancy fuse box includes a plurality of fuse cells, each having a transistor and fuse, to which an address signal of a memory cell is applied. The respective fuse boxes are constructed as one fuse box by being laid out in the same place. The fuse box includes a plurality of fuse cells which receive the same address signal along a common sub-address line and is wired so that outputs of the fuse cells which received the same address signal contribute to different redundancy enable signals.
