Abstract:
A semiconductor device comprisinga plurality of circuit blocks arranged in such a manner that precharging power supply lines which the circuit blocks have, respectively, are connected in common, and the circuit blocks are all of the same structure,a first precharging power supply circuit arranged in such a manner that a precharging current output node thereof is connected to the precharging power supply line, and the first precharging power supply circuit starts its precharging current feed operation when the power supply in the semiconductor chip is turned on, anda second precharging power supply circuit arranged in such a manner that a precharging current output node thereof is connected to the precharging power supply line, and the second precharging power supply circuit starts its precharging current supply operation after the precharging power supply line has been raised to a predetermined potential by the precharging current of the first precharging power supply circuit.
