Detection mechanism of the sector which was eliminated

摘要

This invention includes zero bits of quantities where the sector is low the erroneous operation cell or because of other problem, because the number of bits which are destroyed the ECC correction limit compared to it is under when the sector using, as still the sector which was eliminated immediately and offers non-volatile memory and its operational method of making accurate detection possible. Depending upon this method, the memory system reaches the point where it possesses tolerance vis-a-vis the destruction of the sector which was eliminated. Because, the system, if this error can be corrected is in the entry data due to ECC correction expedient afterwards, can use that kind of sector for further data memory.
