Abstract
A memory controller, upon detecting an interval of inactivity (that is, no read or write access from a processor or I/O devices with respect to main storage or memory SDRAMs) halts external refresh commands from the processor, and initiates STR mode in main storage to preserve data contents in the memory SDRAMs and to save energy. Then, upon detecting a read or write operation, the memory controller signals main storage to exit STR mode.
