<p><P>PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit device capable of solving a restriction that an object once programmed cannot be changed later such as a laser fuse. <P>SOLUTION: The device has a nonvolatile memory area (300) which is electrically erasable and writable and stores adjustment information, memory circuits (TRMR1, TRMR2) which is combined with the nonvolatile memory area so as to receive the adjustment information and stores the adjustment information, and an internal circuit (42) combined with the memory circuit. The adjustment information is transferred to the memory circuit from a nonvolatile memory element responding to the initialization operation of the semiconductor integrated circuit device, and the operation of the internal circuit is controlled by the adjustment information stored in the memory circuit. Thereby, trimming can be freely made by software. <P>COPYRIGHT: (C)2004,JPO</p> |
