Abstract
A semiconductor storage device according to an embodiment comprises: a first memory circuit; a second memory circuit having a storage capacity smaller than that of the first memory circuit; a readout line commonly connected to the first memory circuit and the second memory circuit; a sense amplifier configured to compare a voltage of a first bit signal or a second bit signal with a reference voltage, where the first bit signal being inputted from the first memory circuit through the readout line and the second bit signal being inputted from the second memory circuit through the readout line; and a readout conditioning circuit configured to change at least one of an operation timing of the sense amplifier and the reference voltage corresponding to the first bit signal and the second bit signal.
