2. The nonvolatile storage device according to claim 1,
wherein, if the first writing mode is set in the writing mode table, the control unit performs single level mode writing to the physical address specified from the logicalphysical conversion table, and thereafter copies data of a plurality of blocks with data written therein corresponding to the logical address designated from the access device, to an unused block with no data written therein based on multilevel writing, and
if the second writing mode is set in the writing mode table, the control unit performs multilevel mode writing to the physical address specified from the logicalphysical conversion table.
