Abstract

A highly reliable and high speed ferroelectric memory having high degree of integration is provided. In a ferroelectric memory having a plurality of memory cells M1 each constituted by one transistor and one ferroelectric capacitor. In the normal operation, the ferroelectric memory is used as a volatile memory in which a voltage of a storage node ST1 is utilized as the stored information. Both an electric potential at a plate PL1 of the ferroelectric capacitor and a precharge electric potential on a data line DL1(j) are made Vcc/2.
