Abstract
According to one embodiment, a semiconductor storage device includes a three-dimensional memory cell array, write drivers, and a program voltage control circuit. In the three-dimensional memory cell array, memory cells are three-dimensionally arranged. The write drivers are arranged to be distributed under the three-dimensional memory cell array and apply a program voltage to the memory cells during writing in the memory cells. The program voltage control circuit is arranged around the three-dimensional memory cell array and performs control for making the write drivers to generate the program voltage.
