The invention provides a semiconductor integrated circuit device on which a RAM macro capable of selecting an operation mode adapted to improved ease of use, response, or low power consumption or selecting an input setup value is mounted. In a first operation mode of a RAM macro, a timing of receiving an input signal is set as a first timing. In a second operation mode, a timing of receiving an input signal is set to a second timing later than the first timing. In a semiconductor integrated circuit device including an input circuit for receiving an input signal and a decoder circuit for decoding an output signal of the input circuit, the input circuit is activated on the basis of a first signal and the decoder circuit is activated on the basis of a second signal.
