<p>PURPOSE:To easily secure a data storage part to be used afterward without storing dummy data by storing information indicating data length as specific information when there are no data. CONSTITUTION:In case of storing data in a nonvolatile memory, storage data and information indicating its data length l are simultaneously stored, and when there are no data, the information indicating the data length is stored as specific information. Namely, the length information of storage data is stored as specific information such as '0' and normal information is executed. Consequently, the data storage part to be used afterward can be easily secured without storing dummy data. Normal operation such as storage in the data storage part following the secured data storage part can be executed without being conscious of the secured data storage part.</p> |
