Abstract

According to an embodiment, a semiconductor storage device includes a first memory cell and a control circuit. The first memory cell is configured to store first data. The control circuit is configured to apply a first voltage to a source of the first memory cell in a read operation of the first data in the first memory cell, and to apply a second voltage to the source of the first memory cell in a verify operation of the first data in the first memory cell. The second voltage is lower than the first voltage.
