Disclosed is a method which uses less system bus bandwidth for memory refresh by automatically detecting when a staggered refresh is required to minimize power supply current requirements. This method relates to a PS/2 computer containing sockets for Single In-line Memory Modules (SIMMs). Each SIMM may contain 1 megabyte, 2 megabytes, or 4 megabytes of dynamic RAM, which require periodic refresh cycles.
