Abstract
A memory capable of easily setting a reference potential and correctly determining data is provided. This memory comprises a ferroelectric capacitor holding data, and a driving line and a data line linked with the ferroelectric capacitor. The memory applies a voltage pulse to the ferroelectric capacitor through the driving line when reading the data thereby generating a negative potential on the data line if the ferroelectric capacitor holds first data, or generating a positive potential on the data line if the ferroelectric capacitor holds second data.
