An information processing apparatus has a multi-valued NAND nonvolatile memory including a plurality of word lines and a plurality of memory cells connected to the respective word lines. Each memory cell has a plurality of threshold voltages, and is divided into a first and a second storage area. A program code is stored in the first storage area, and user data is stored in the second storage area. The apparatus also includes a volatile memory to which the program code is transferred from the multi-valued NAND nonvolatile memory. The apparatus further includes a CPU connected to the volatile memory and configured to operate based on the program code transferred to the volatile memory.
