US Patent 7305518 Method and system for dynamically adjusting DRAM refresh rate

One embodiment is a method of dynamically adjusting a rate at which a dynamic random access memory (“DRAM”) module is refreshed in a computer system. The method comprises monitoring a plurality of system conditions; detecting a change in at least one of the monitored system conditions; responsive to the detection, determining an optimum refresh rate for a current state of the computer system; and setting the refresh rate to the determined optimum refresh rate.
