One of objects is to provide a nonvolatile memory device in which the occurrence of a defect in data writing is suppressed and whose area can be suppressed, or a semiconductor device including the nonvolatile memory device. The construction includes a separate cover portion for the cushion of a sofa which has a L-shaped rear wall which maintains the cover in position when the cushion is sat upon by allowing material to expand forwardly over an upper surface of said cushion to retract when the furniture is vacated. First and second nasal locators extend in opposite directions from the holder. The IC die is mounted to the first surface of the substrate in a flip chip orientation. In some embodiments the first domain is a secure domain and the second domain is a non-secure domain, the monitoring function being debug or trace. Various other systems, methods, and computer-readable media are also disclosed.
