SEMICONDUCTOR DEVICE AND CURRENT AMOUNT CONTROL METHOD

摘要

There is provided a semiconductor device including: a current generation circuit that generates a current; a voltage generation circuit that, using the current generated by the current generation circuit, generates and outputs a predetermined voltage from a reference voltage, with an internal capacitor element that is connected to output of the voltage generation circuit, the internal capacitor element being provided within an integrated circuit on which the device itself is mounted; a storage section that stores a flag indicating a connection state between the output of the voltage generation circuit and an external capacitor element provided externally to the integrated circuit; and a controller that, based on the flag, controls a current amount of the current used by the voltage generation circuit to generate the predetermined voltage.
