Abstract
A memory card includes a first nonvolatile memory, a second nonvolatile memory, and a separating portion. The first nonvolatile memory has a predetermined erase unit. The second nonvolatile memory has an erase unit that is larger than the erase unit of the first nonvolatile memory. The separating portion separates at least the portion of the program data that are downloaded onto the memory card that has the possibility of being rewritten, and stores the separated portion onto the first nonvolatile memory and stores the remaining portion onto the second nonvolatile memory.
