Abstract
In a ferroelectric memory, a malfunction in which data are reversed at the time of writing after reading out of data is prevented. Using a transistor to short-circuit two common lines which are connected to a memory element, the two common lines are short-circuited at the preparing stage for writing new data, and thereby such a malfunction which occurs reversal of data owing to an electric potential difference between common lines is prevented.
