MEMORY REWRITING APPARATUS

摘要

Even in a cellular terminal having no data rewriting function, a memory rewriting apparatus can rewrite data stored in a memory of the cellular terminal completely without stopping in the middle. According to the model type and the version number of data stored for each area, a memory area requiring update is specified (step S3). A battery amount required for rewrite/update the data of the memory area specified is calculated (step S4). The calculated battery amount is compared to the acquired current battery remaining amount and if the battery remaining amount is sufficient (Yes in step S5), data for the specified memory area is transmitted to the cellular telephone and the memory area to be updated is specified (step S6).
