Semiconductor integrated circuit

Abstract

A nonvolatile semiconductor memory concerning an example of the present invention comprises a cell array, a plurality of conducting wires extending from the cell array to a lead area, and a plurality of contact holes to arranged in the lead area so that a distance from the end of the cell array sequentially increases from one to the other of the plurality of conducting wires, each of the plurality of conducting wires having a first conducting wire portion having a first conducting wire width, a second conducting wire portion connected to the contact hole and having a second conducting wire width smaller than the first conducting wire width, and a third conducting wire portion electrically connecting the first conducting wire portion to the second conducting wire portion.

Dependencies are inferred from the claim text.
