    Abstract: A semiconductor storage device includes memory cells a controller performing a write operation on the memory cells. The write operation includes program loops with a program operation and a verification operation. In a first loop the controller applies a first program voltage and a first verification voltage. Next, a detection operation counts the memory cells with a threshold voltage above a first threshold value. In a second program loop, after the detection operation, the controller applies a second program voltage and a second verification voltage. The values of used for second program voltage and the second verification voltage are set dependent on the counted number of memory cells with a threshold voltage above the first threshold value.
