Abstract
A semiconductor storage device includes a first word line, a first insulating layer extending along the first word line, a first memory cell connected to the first word line, a second memory cell connected to the first word line, a first bit line connected to the first memory cell, a second bit line connected to the second memory cell, and a control circuit. The second memory cell is farther from the first insulating layer than the first memory cell. The control circuit is configured to apply a first voltage to the first bit line during a read operation of the first memory cell, and apply a second voltage to the second bit line during a read operation of the second memory cell. The second voltage is higher than the first voltage.
