A method, system and computer program product are provided for implementing ECC (Error Correction Codes) memory module communications with a host processor in multi-ported memory configurations in a computer system. Each of multiple memory modules operating in unison is enabled to identify which memory module is the one required to communicate module specific information back to the host processor. All of the multiple memory modules operating in unison are enabled to generate back to the host processor a valid ECC word, while other multiple memory modules individually being unaware of data contents of the one memory module required to communicate back to the processor.
