ABSTRACT:
A ferroelectric memory is described which has a memory array arranged in rows and columns. The memory array includes a plate line which is segmented into sub-plate lines which correspond to a row of the memory. The plate line segments have multiple driver circuits coupled thereto for providing a plate line voltage signal. The memory array can include a global plate line coupled to the segments of the segmented plate line via an access switch, or transistor. A global plate line voltage is controlled by multiple plate line driver circuits.
