ABSTRACT:
A semiconductor integrated circuit device includes a plurality of memory cells which have two or more layout patterns and are arranged to make different patterns adjacent to each other, each of the memory cells having a transistor and a ferro-electric capacitor, a plurality of bit lines connected to the memory cells, and a plurality of sense amplifiers each of which is arranged in correspondence with a pair of bit lines connected to the memory cells having the same pattern and uses one of the pair of bit lines as a main input and the other of the pair of bit lines as an input complementary to the main input.
