Provided is a nonvolatile memory device, including a memory cell array region, a decoder and an interface region. The memory cell array region includes multiple word lines. The decoder supplies multiple voltages to the word lines through multiple first type metal lines formed of a first metal and multiple second type metal lines formed of a second metal. The interface region connects the first type metal lines to first word lines in a first group, and connects the second type metal lines to second word lines in a second group. The first type metal lines are sequentially disposed to correspond with a positioning order of the first word lines in the first group, and the second type metal lines are sequentially disposed to correspond with a positioning order of the second word lines in the second group.
