ABSTRACT:
A technique for resynchronizing a memory system. More specifically, a technique for resynchronizing a plurality of memory segments in a redundant memory system after a hot-plug event. After a memory cartridge is hot-plugged into a system, the memory cartridge is synchronized with the operational memory cartridges such that the memory system can operate in lock step. A refresh counter in each memory cartridge is disabled to, generate a first refresh request to the corresponding memory segments in the memory cartridge. After waiting a period of time to insure that regardless of what state each memory cartridge is in when the first refresh request is initiated all cycles have been completely executed, each refresh counter is re-enabled, thereby generating a second refresh request. The generation of the second refresh request to each of the memory segments provides synchronous operation of each of the memory cartridges.
