Abstract: Systems, methods, and computer programs are disclosed for reducing power consumption for static image display refresh in a dynamic random access memory (DRAM) memory system. One such method comprises: prefetching static image frame content from a DRAM memory device into a system cache; during a static display refresh operation, a display processor reads the static image frame content from the system cache while the DRAM memory device is in a power-saving, self-refresh state; and the display processor feeding the static image frame content to a mobile display.
