On object of the invention is to provide a nonvolatile memory device, in which data can be added to the memory device after a manufacturing process and forgery and the like by rewriting can be prevented, and a semiconductor device including the memory device. The invention advantageously provides enhanced Quality of Service by opportunistically avoiding signal degradation where VoDSL to VoDSL gateway communications may be provided. This expandable tip can retrieve or deliver samples, medical devices, etc. The digital watermark is embedded in the digital imagery through modifications to at least some data representing the digital imagery.
