Abstract
A semiconductor memory that includes a memory cell array by which power consumption can be reduced and that enables a reduction in circuit area. In the memory cell array, each of capacitor plate lines is arranged so as to connect with ferroelectric memory cells in a same row, and each of word lines is arranged so as to connect with ferroelectric memory cells in different rows in a column direction. In addition, of drive circuits for driving the capacitor plate lines and the word lines, part of word line drive circuits (WL drive circuits) are arranged in the column direction. Therefore, it is possible to drive all of the word lines without using a dummy area. As a result, circuit area can be reduced.
