ABSTRACT:
A nonvolatile storage device includes a first memory and a second memory in addition of a memory cell array. The first memory stores original data and the original data is copied onto the second memory. The original data stored in the first memory is compared with read data in bits to produce a comparison result for each bit. The copied original data stored in the second memory is reset in bits depending on the comparison result for each bit to produce write data to be written onto the addressed memory cells.
