Abstract
The present invention realizes a semiconductor integrated circuit device for driving liquid crystal (liquid crystal control driver IC) capable of easily setting drive conditions and the like according to specifications of a liquid crystal display to be used. An electrically-programmable nonvolatile memory circuit (EPROM) or an electrically erasable and programmable nonvolatile memory circuit (EEPROM) is provided in a semiconductor integrated circuit device for driving a liquid crystal display, and setting information is stored in the memory circuit. The memory circuit is constructed by a normal device which can be formed in the same process as a semiconductor manufacturing process of forming devices of other circuits.
