Abstract
A method includes temporarily storing write-data to be written into non-volatile memory cells, respectively, the memory cells being divided into cell groups, performing a first operation including write-phases performed in series and on an associated cell group and including applying a write-voltage to the memory cells belonging to the associated cell group in response to an associated write-data to be written into the memory cells belonging to the cell groups, and performing a second operation after the first operation is completed, which includes read-phases performed in series and on an associated cell group and including applying a first read-voltage to the memory cell or cells belonging to the associated one of the cell groups to produce first read-data therefrom, and comparing the first read-data with the write-data to be written into the memory cells belonging to the associated cell groups to produce comparison data.
