Abstract: A memory module contains a first interface for receiving data access commands and a second interface for re-transmitting data access commands to other memory modules, the second interface propagating multiple copies of received data access commands to multiple other memory modules. The memory module is preferably used in a high-capacity memory subsystem organized in a tree configuration in which data accesses are interleaved. Preferably, the memory module has multiple-mode operation, one of which supports multiple replication of commands and another of which supports conventional daisy-chaining.
