Patent ID: 7345931

Claim:
A method for controlling an output reference voltage generated by a reference voltage generator disposed on a device, comprising: receiving a signal for enabling a clocked standby mode of the device; if the signal indicates that the device is in the clocked standby mode, generating a first reference voltage as the output reference voltage of the reference voltage generator; and if the signal indicates that the device is not in the clocked standby mode, generating a second reference voltage as the output reference voltage of the reference voltage generator, wherein the first reference voltage is larger than the second reference voltage; and wherein: a voltage generation circuit maintains an output voltage using the generated output reference voltage, the voltage generation circuit being selectively enabled or disabled by a clocked standby mode signal when the device is in the clocked standby mode, and the first reference voltage compensates for a voltage drop in the output voltage generated by the voltage generation circuit resulting from selectively enabling and disabling the voltage generation circuit.
