The DIMM tree architecture was proposed to overcome the drawbacks of the traditional DIMM interface methods such as multi-drop bus and point-to-point links. As the DIMM tree architecture has a tree topology, the most important function of the DIMM tree architecture is the command routing function between upper-level and lower-level DIMMs. In order to implement this function, it uses a special type of DIMMs, called tree DIMMs (T-DIMMs). However, because the pre-proposed T-DIMM uses the command routing method based on routing tables, some problems occur such as hardware cost increase due to the routing table, routing table initialization, and limitation in the number of ranks in one T-DIMM. To solve such problems, this paper proposes a command routing method based on a T-DIMM ID without the routing table. The proposed method was modeled with a register transfer model (RTL). The model of the proposed method has 2 ranks per T-DIMM, and doesn’t use the routing table for command. This RTL model was synthesized into the gate-level model. The experimental results confirmed that hardware cost of the proposed method is reduced dramatically while its performance is the same, as compared with the previous routing method in the DIMM tree architecture.
