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