A ferroelectric memory device equipped with: a voltage source for generating a predetermined voltage; a first ferroelectric capacitor having one end electrically connected to a first bit line; a first resistance having a first resistance value, provided between the first bit line and the voltage source; a second ferroelectric capacitor having one end electrically connected to a second bit line; a second resistance having a second resistance value different from the first resistance value, provided between the second bit line and the voltage source; and a sense amplifier that judges data written in the first ferroelectric capacitor by comparing a potential on the first bit line with a potential on the second bit line when the predetermined voltage is supplied to the first bit line and the second bit line.
