Abstract
A system, and a corresponding method, are used to implement rank sparing. The system includes a memory controller and one or more DIMM channels coupled to the memory controller, where each DIMM channel includes one or more DIMMS, and where each of the one or more DIMMs includes at least one rank of DRAM devices. The memory controller is loaded with programming to test the DIMMs to designate at least one specific rank of DRAM devices as a spare rank.
