Abstract:
A memory rewriting apparatus comprising:copying means for copying a rewriting program stored in a nonvolatile memory into a RAM upon receipt of an instruction for rewriting said nonvolatile memory; a RAM allocation means for allocating said RAM, into which copying is carried out by said copying means, to an area of said nonvolatile memory; and rewriting execution means for rewriting said nonvolatile memory by using said rewriting program stored in said RAM by said RAM allocation means, wherein said copying means copies said rewriting program by copying information stored in a predetermined region of said nonvolatile memory allocated for said rewriting program, and wherein said RAM allocation means allocates said RAM to the area of said nonvolatile memory such that said rewriting program stored in said RAM by said copying means is memory mapped to said predetermined region of said nonvolatile memory when said rewriting execution means performs the rewriting of the nonvolatile memory.
