SEMICONDUCTOR INTEGRATED CIRCUIT

摘要

Disclosed is memory having an internal power supply circuit mounted therein wherein at the time of supplying power to the memory by generating an internal power supply on the basis of an external power supply, power is stably supplied from the internal power supply, while reducing the circuit area and suppressing an increase of power consumption. In the memory, when the external power supply (102) is within a first voltage range, the internal power supply (103) is generated using only an internal step-down power supply block (101), and when the external power supply (102) is within a second voltage range, which is lower than the first voltage range, the internal power supply (103) is generated using an internal step-up power supply block (112) in addition to the internal step-down power supply block (101).
