Abstract
A memory system comprising an expansion buffer and a memory expansion channel for connecting a large array of memory devices, such as Direct RDRAMs, to a memory controller. The memory devices are partitioned into subsets of memory devices so that each subset is connected to a unique memory channel for sending and receiving data. The expansion buffer and memory expansion channel provide communication with the memory devices via control packets on the expansion bus, where each control packet has a channel identification field to store a channel identifier; and via request packets on the expansion bus, where each request packet is associated with a control packet. The expansion buffer routes a request packet to a unique channel based upon the channel identifier stored in the associated control packet.
