A semiconductor storage device includes first and second memory cells, first and second word lines connected to the first and second memory cells, respectively, a bit line connected to the first and second memory cells, and a sense amplifier including a sense node. During a first read, a controller applies a first read voltage to the second word line and determines a read result. During a second read, the controller discharges the sense node for a first time period while applying a second read voltage to the first word line to determine a first read result, and discharges the sense node for a second time period while applying the second read voltage to determine a second read result. The controller determines read data based on the first read result, the second read result, and the read result of the second memory cell.
