ABSTRACT:
The semiconductor integrated circuit device formed on one semiconductor substrate employs a plurality of first and second circuit blocks constituting functions of the same kind. The first and second circuit blocks, however, are implemented with respectively different types of circuits. The type of circuit employed in the respective first and second circuit blocks is necessarily consistent with the particular operation speed requirements thereof, such as, in connection with high-speed and low-speed circuit requirements for writing into the memory of a display system.
