PPROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit device which uses a plate line in common while achieving relatively small memory cells and is operated at high speed by eliminating delay caused by series connection of the memory cells. PSOLUTION: The semiconductor integrated circuit device includes: a plurality of first memory cells each of which includes cell transistors Q0-Q3 whose gate terminal is connected to a word line; and ferroelectric capacitors C0-C3 which are connected at one end to a source terminal of the cell transistor. The drain terminal of each of the cell transistors of the plurality of first memory cells is used as a first local bit line LBL, and the other end of each of the ferroelectric capacitors is used as a first plate line PL. A first reset transistor has a source terminal connected to the first plate line and also a drain terminal connected to the first local bit line. A first block selection transistor QS has a source terminal connected to the first local bit line, and also has a drain terminal connected to the first bit line. PCOPYRIGHT: (C)2008,JPO&INPIT
