<p>PURPOSE:To shorten the processing time required for re-erasure after memory erasure interruption and reproduce residual data. CONSTITUTION:Several addresses from the tail address on the flash memory card 1 which has plural flash memory ICs 7a-7h are used as an erasure area recording area, wherein erasure completion information is recorded in order each time the memory of a flash memory IC is erased. After the erasing process is interrupted for some reason, the erasure completion information can be read out when re-erased, and the erasing process of only an unerased flash memory IC can be performed.</p> |
