CA 2707914

Techniques pertaining to adjusting the operation frequency of a DRAM are disclosed. According to one embodiment, the DRAM operation frequency adjusting system includes a statistic module counting effective operations of a DRAM to obtain a bandwidth utilization rate of the DRAM at a present operation frequency; a parameter configuration module including a target frequency configuration sub-module configured to generate a target operation frequency; and a frequency switch controller for switching a present operation frequency of the DRAM to the target operation frequency. The invention adjusts the operation frequency of a DRAM according to the application environment, and creates a balance between performance and power consumption of DRAMs, and thus improves operation speed of system-on-chips as well as decreases the power consumption.
