NAND type non-volatile ferroelectric memory cell and non-volatile
ferroelectric memory of the same, in which numbers of access to a main
cell and a reference cell are made the same, to maintain bitline induced
voltages by the reference cell and by the main cell constant, for
improving operation characteristics, minimizing a layout area, and permits
a high density device integration, the memory cell including an N number
of transistors connected in series, a bitline having an input terminal of
a first transistor and an output terminal of (N)th transistor among the N
number of transistors connected thereto, wordlines respectively connected
to gates of the transistors except the (N)th transistor, a WEC signal line
connected to a gate of the (N)th transistor and adapted to have an enable
signal applied thereto only in a write or re-store mode, and ferroelectric
capacitors respectively connected both to the wordlines and output
terminals of the transistors.
