This paper proposes a new dual-gate cell (DGC) FeRAM. The dual-gate cell is composed with MFSFET and MOSFET faced in parallel with common drain, source and float channel. The gates of the dual-gate cell are controlled by wordline and bottom wordline, respectively. A multitude of the dual-gate cells are arrayed in serial connection for unit array scheme. The WL 1 to WL m of MFSFET are not biased for sensing operation in read mode, thus there are no degradation and disturbance to the cell retention data in read access. The write cycle composed with two sub-write cycles of data '1' preserve or data '0' write cycle after the first sub-write cycle of data '1' write to all active cells. The data '1' is preserved by the same voltage polarity between WL 1 and channel voltage of the MFSFET. The random access operation is possible in both read and write mode with non-destructive read out (NDRO).
