Abstract
At a time of writing first data to a first memory cell, second data which is written later to an adjacent second memory cell is referred to, and when a value of the second data corresponds to a first threshold level, a verify voltage is set to a first verify voltage, and when the value of the second data corresponds to a second threshold level greater than the first threshold level, the verify voltage is set to a second verify voltage smaller than the first verify voltage.
