Abstract
A ferroelectric memory which can ensure a sufficient operational margin at the time of a read operation, includes a transmission transistor and a ferroelectric capacitor which are connected in series between a bit line and a plate electrode. Composite data of a pair of reference cells storing reverse data with each other and data of a read cell are compared before reading out data of a memory cell.
