Example Embodiment

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0024] In the following description, many specific details are set forth in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described here, so the present invention is not limited by the specific embodiments disclosed below.

[0025] As mentioned in the background art section, in the charge pump system used in the memory in the prior art, the same clock driving device controlled by the same power supply voltage is used to generate the charging clock signal and transmit the clock signal, which will cause the charging efficiency and / Or the transmission efficiency is reduced.

[0026] To solve the above problems, the present invention provid

Abstract

A charge pump system and memory, the charge pump system comprising: a charge pump unit; a clock drive device connected to the charge pump unit, the clock drive device has: a first clock drive unit controlled by a first power supply voltage , enhance the obtained current of the first type clock signal and output it to the charge pump unit; the second clock driving unit controlled by the second power supply voltage enhances the obtained current of the second type clock signal and output it to the said charge pump unit A charge pump unit; a power supply voltage stabilizing unit, configured to adjust the second power supply voltage to obtain the first power supply voltage. Compared with the prior art, the present invention improves charging efficiency and transmission efficiency by setting the first clock driving unit and the second clock driving unit separately and providing different power supply voltages respectively.
