ABSTRACT:
A semiconductor integrated circuit configured for connection to an external ROM includes a decryption code block storing a decryption code; a decoder circuit connected to the decryption code block and decrypting encrypted data such that the encrypted data can be stored in the external ROM, by utilizing the decryption code; a configuration circuit connected to the decoder circuit; an FPGA circuit connected to the configuration circuit, the circuit structure of the FPGA circuit determined by the configuration circuit; and an internal circuit connected to the FPGA circuit, the circuit operation of which is determined by the FPGA circuit.
