Before a first process causing reliability degradation is performed, a first write operation is performed such that first data having a first threshold voltage distribution is stored into memory cells connected to first wordlines. The first wordlines have a degree of reliability degradation less than a reference value. Before the first process is performed, a second write operation is performed such that second data having a second threshold voltage distribution is stored into memory cells connected to second wordlines. The second wordlines have a degree of reliability degradation greater than or equal to the reference value.
