Abstract
A semiconductor storage device includes a bit line, a memory cell transistor electrically connected to the bit line, and a sense amplifier that reads data from the memory cell transistor via the bit line. During an operation of determining first data and second data, while continuously applying a first voltage to a gate of the memory cell transistor, the sense amplifier first determines the first data based upon a second voltage, and then determines the second data based upon a third voltage lower than the second voltage.
