Abstract:
1. A control method of a non-volatile memory apparatus comprising: a controlling step of controlling data writing and data readout of a non-volatile memory, by using an erased table and a logical address/physical address conversion table, the non-volatile memory having a plurality of physical blocks, each physical block being an erasing unit of data, the erased table indicating whether the physical blocks are erased or not, the logical address/physical address conversion table converting a logical address to a physical address; a writing step; the writing step of including: an initialization step of reading out said first flag of all said physical blocks of said non-volatile memory at the startup of the non-volatile memory apparatus, and generating the logical address/physical address conversion table and the erased table based on whether said first flag is written or not.
