Patent ID: 8659971

Claim:
A word-line voltage regulating circuit for single power supply memory, comprising: a charge pump for raising an input voltage to a desired value and outputting the raised input voltage as an output voltage; a controller for inputting a refresh signal to the charge pump according to the output voltage of the charge pump; and a comparator for inputting a feedback signal to the charge pump according to a comparison result between the output voltage of the charge pump and a reference voltage, wherein, a read control signal controls the controller and the comparator, so as to deactivate the controller and activate the comparator when the single power supply memory is in an active mode, and to activate the controller and deactivate the comparator when the single power supply memory is in a standby mode, and wherein the charge pump works under control of the refresh signal in the active mode, and works under control of the feedback signal in the standby mode.
