Abstract
In developing the function of a data processing system using a semiconductor integrated circuit for data processing, comprising a non-volatile logical function block to which data is written electrically and a logical operation block utilizing the logical function block to execute the logic operation, data corresponding to the required specification and function of the system is written in the logical function block. Thereby, flexibility is obtained for setting and changing the required function to the semiconductor integrated circuit. The semiconductor integrated circuit also has an operation specification written to the logical block by a writing device designed to write to a non-volatile semiconductor storage device thereby improving the convenience of setting the functions required of the semiconductor integrated circuit.
