WebSelf Refresh is a low power state for the DDR memory in which you can't perform any accesses. The idea is to save power when you have a system that intermittently needs to use the DRAM. Self-Refresh saves the memory contents while in a low power state and then can quickly return to an active state to service the needs of the system.
