Abstract
The invention provides a memory apparatus, a charge pump circuit, and a voltage pumping method thereof. The charge pump circuit including a plurality of delay units, a latch circuit, and a plurality of charge pump units. The delay units respectively generate a plurality clock signals according to an output clock signal. The latch circuit receive a final stage clock signal of the clock signals and a latch enable signal. The latch circuit decides whether to latch final stage clock signal or not to generate the output clock signal according to the latch enable signal. The first stage of the charge pump unit receives an input voltage, and the charge pump units operate a voltage pumping operation on the input voltage to generate an output voltage according to the clock signals and the output clock signal.
