Abstract

A semiconductor integrated circuit device has a data storage section for storing mode setting data corresponding to products of a plurality of types, redundancy data, and so on. The redundancy storage section is made up of a nonvolatile transistor for storing the mode setting data corresponding to the products, the redundancy data, etc., a latch circuit for latching data read out from the nonvolatile transistor and generating a mode signal, and a transmission gate for transmitting the data from read out from the nonvolatile transistor to the latch circuit. The semiconductor integrated circuit device also has an internal voltage generator for generating an internal voltage. This internal voltage is used as the power supply voltage of the data storage section.
