A semiconductor storage device precharging a bit line pair to a ground potential includes a sense amplifier connected between the bit line pair, a storage cell connected to one of the bit line pair and storing data, a first transistor controlling a conduction state between the other of the bit line pair and a reference cell node, a second transistor connected between a reference voltage source generating a reference voltage and the reference cell node, the second transistor exclusively controlled from the first transistor, and a capacitor setting a potential of the reference cell node.
