ABSTRACT:
A control method of a non-volatile memory apparatus, which can execute data writing normally after the next startup even when a process is interrupted because of the occurrences of abnormal conditions such as power shut down during data writing or data erasing is provided. The control method of a non-volatile memory apparatus of the present invention comprises: a first flag writing step of writing a fixed value, which indicates that data is written, on a first flag existing in a redundancy area on a first page of a physical block and indicating whether or not data is written on the first page; and a data writing step of writing data on the physical block, when the data is written on the non-volatile memory consisting of a plurality of physical blocks.
