... There is a via grid located under the DRAMs for wiring the CA signals (address, bank address, command, and control lines) to the DRAM pins. The length of the traces from the vias to the DRAMs places limitations on the bandwidth of the module. The shorter these traces, the higher the bandwidth. To extend the bandwidth of the CA bus for DDR3 modules, a scheme was defined to reduce the length of these traces ...
