摘要

At only the block unit from the 1st block where, the effective data and the null data among the NAND die flash memories whose data erasure is possible exist together, to copy the effective data to main memory, that access to the copy original effective data it rejects controls to specify to exclusive feature, from the copy original effective data, to change access path to the effective data ahead the copy, that control of exclusion is released to exclusive feature, specify, to copy the effective data ahead the copy, in the 2nd block which is block of NAND die flash memory from main memory, 2ndThat access to the copy original effective data being copied to block it rejects controls you specify to exclusive feature, from the copy original effective data which is copied to 2nd block, you change access path to the effective data ahead the copy which was copied to 2nd block, that control of exclusion is released to exclusive feature, the fact that you specify you have the computer run.
