Abstract
A semiconductor storage device has a bit line, a source line, a first memory cell and a second memory cell provided between the bit line and the source line and connected in series, a first word line connected to the first memory cell, a second word line connected to the second memory cell, and a control circuit. The control circuit, when executing a read operation with respect to the first memory cell, supplies a source voltage to the source line, supplies a first voltage to the first word line, and supplies a second voltage to the second word line, and a difference between the source voltage and the second voltage is smaller than a difference between the source voltage and the first voltage.
