Abstract

An object of the present invention is to realize a highly reliable long-life information processor capable of high-speed operation and easy to handle. The processor includes a semiconductor device comprising a nonvolatile memory device including a plurality of overwritable memory cells, and a control circuit device for controlling access to the nonvolatile memory device. The control circuit device sets assignments of second addresses to the nonvolatile memory device independently of first addresses externally supplied, such that the physical disposition of part of the memory cells used for writing of first data to be written externally supplied is one of the first to (N+1)th of every (N+1) memory cells (N: a natural number) at least in one direction.
