Abstract
A semiconductor storage device includes a memory transistor and a word line connected to a gate electrode of the memory transistor. When a write sequence is interrupted before a k+1verification operation is ended after a kverification operation is ended in the nwrite loop of the write sequence, a voltage equal to or higher than a verification voltage corresponding to a first verification operation in the nwrite loop is supplied to the word line before start of the k+1verification operation after resumption of the write sequence. A time from the resumption of the write sequence to the start of the k+1verification operation is shorter than a time from start of the first verification operation to end of the kverification operation in the nwrite loop.
