Abstract
Charge pump system and memory are provided. The system includes: a first enabling control unit, adapted to delay at least one start-up signal of the system to obtain and output an oscillating enabling signal after receiving the at least one start-up signal and a voltage boosting enabling signal; a second enabling control unit, adapted to delay the oscillating enabling signal to obtain and output a charge pump enabling signal after receiving the oscillating enabling signal and the voltage boosting enabling signal; a clock oscillating unit, adapted to generate a clock signal after receiving the oscillating enabling signal; and at least one charge pump cell, adapted to output a boosting voltage after receiving the charge pump enabling signal and the clock signal, obtain the voltage boosting enabling signal based on the boosting voltage, and output the voltage boosting enabling signal. Power consumption of the system in a start-up process is reduced.
