Abstract
A power circuit and a memory device using the same are provided. The power circuit is used for providing an operating voltage to a memory array, and includes a voltage regulator circuit and a voltage feedback circuit. The voltage regulator circuit receives a system voltage to provide the operating voltage. The voltage feedback circuit is coupled to the voltage regulator circuit to receive the operating voltage, and receives a data locking voltage, wherein the voltage feedback circuit has a non-volatile memory element which is set or reset in response to the data locking voltage. The voltage feedback circuit is set or reset based on the non-volatile memory element to provide a feedback voltage to the voltage regulator circuit, so as to set an output level of the operating voltage.
