ABSTRACT:
A ferroelectric memory device includes a plurality of memory cells, each memory cell includes a ferroelectric capacitor and a transistor, a plate line drive unit capable of providing a first voltage to the memory cell array in response to a plate line drive signal, and a reference voltage generating device. The reference voltage generating includes a reference cell block having a plurality of reference cells, each reference cell including a ferroelectric capacitor and a transistor, and a reference plate line drive to provide a reference plate line voltage to at least one reference cell in response to a plate line drive signal and a reference voltage generation signal, where each reference cell generates a reference voltage in response to the reference plate line voltage.
