摘要：
A data processor includes an authentication function for judging access right. The data processor further includes a nonvolatile memory cell array formed on an insulator film or a chip, and a conductor layer provided between a logic circuit for the authentication and the nonvolatile memory. The nonvolatile memory can store at least part of authentication information or an authentication program.
