Abstract
A semiconductor storage device includes a first memory cell electrically connected to a first bit line and a first word line, a second memory cell electrically connected to a second bit line and the first word line, and a first circuit configured to supply voltages to the first word line. During a reading operation to read a page of memory cells including the first memory cell and the second memory cell, the first circuit supplies a first voltage to the first word line while the first memory cell is selected as a read target during a first time period, and supplies a second voltage greater than the first voltage to the first word line while the second memory cell is selected as a read target during a second time period that is different from the first time period, and directly thereafter, supplies the first voltage to the first word line.
