Semiconductor integrated circuit which allows adjustment of circuit characteristics in accordance with storage data of nonvolatile memory element

摘要

The invention provides a semiconductor integrated circuit, characteristics of which can be adjusted in accordance with storage data in a nonvolatile memory element. The semiconductor integrated circuit has a main semiconductor circuit having MOS transistors, and an adjusting circuit connected to the main semiconductor circuit so as to change the circuit characteristics of the main semiconductor circuit as needed. The adjusting circuit has MOS transistors and a plurality of fuse elements. The adjusting circuit causes a given fuse element to selectively disconnect in accordance with an input signal and generates at least one adjusting signal to adjust the circuit characteristics of the main semiconductor circuit.
