Abstract
The present disclosure provides a pump circuit comprising a temperature-sensing module, an oscillating module and a pumping module. The temperature-sensing module is configured to measure a temperature of a dynamic random access memory (DRAM). The oscillating module is coupled to the temperature-sensing module and is configured to generate a clock signal based on the temperature of the DRAM. The pumping module is coupled to the oscillating module and is configured to generate a pump voltage and a pump current to drive the DRAM, wherein the pump current is generated based on an oscillating frequency of the clock signal. When the temperature of the DRAM changes, the oscillating frequency of the clock signal changes based on the temperature of the DRAM, and the pump current correspondingly changes based on the oscillating frequency of the clock signal.
