Abstract: A voltage booster and a memory structure using the same are provided. When a data storage unit in the memory structure is in normal operation, all voltage pumps in the voltage booster are turned on for boosting a supply voltage. However, when the data storage unit is in standby state, in the voltage booster, some voltage pumps are turned on while other voltage pumps are turned off, for boosting the supply voltage. Accordingly, the standby current and power consumption are reduced and the pump efficiency is improved.
