Abstract

The invention relates to a power supply adjusting circuit and method and a memory. The power supply adjusting circuit comprises a frequency control module, a clock module and a charge pump, the frequency control module is used for determining the frequency of the memory according to the configuration value of the column address command time interval of the memory; the clock module is connected with the frequency control module and is used for outputting a clock signal with a specified frequency according to the frequency of the memory; and the charge pump is connected with the clock module, and the clock signal is used for controlling the charge pump to carry out boosting operation on the power supply voltage and outputting a trigger power supply. According to the invention, real-time adjustment of the working frequency of the charge pump is realized, and the transient response speed of the trigger power supply when the working frequency of the memory changes is improved. And the working frequency of the charge pump is adjusted in real time according to the working frequency of the memory, so that noise on the trigger power supply is reduced.

Description

technical field [0001] The present disclosure relates to the technical field of memory, and in particular, to a power regulation circuit and method, and a memory. Background technique [0002] With the development and progress of technology, memory chips are more and more widely used in various electronic products. During the working process of the memory, the switching frequency of the word line is related to the working frequency of the memory chip. The trigger power supply VPP is the Turning on provides a high-voltage power supply, so the stability of the trigger power supply VPP is very important for the normal operation of the memory chip. [0003] At present, during the working process of the memory chip, the voltage amplitude of VPP is usually monitored dynamically in real time, and then the oscillation clock of the charge pump circuit is controlled to be turned on or off, so as to obtain a stable trigger power supply VPP. However, when the operating frequency of the...
