MEMORY INTERFACE MAPPING

Abstract:

System connections map interface connections between the memory device and the memory controller. The memory controller is configured with information about these `mapped` connections. The memory controller uses the mapping information to: correctly present commands and addresses to the memory device, perform CA training on mapped connections, generate read training data that accounts for mapped connections, correctly address mapped memory device pins for write training per pin adjustments, correctly calculate error detection coding, and correctly read vendor identification information.
