POWER SUPPLY CIRCUIT AND SEMICONDUCTOR MEMORY DEVICE INCLUDING THE SAME

摘要

PURPOSE: A power supply circuit and a semiconductor device including the same are provided to suppress a switching noise by turning on switches in a power supply circuit. CONSTITUTION: A plurality of switches(201-204) transfer voltage of a power voltage terminal to an inner voltage terminal. A switch control unit(210) turns on two or more switches at different time. A plurality of switches are turned on after preset time elapses from the activation time of a voltage supply signal. A plurality of delay units successively delay a voltage supply signal.
