    Abstract: A memory controller and buffers on memory modules each operate in two modes, depending on the type of motherboard through which the controller and modules are connected. In a first mode, the controller transmits decoded chip-select signals independently to each module, and the motherboard data channel uses multi-drop connections to each module. In a second mode, the motherboard has point-to-point data channel and command address connections to each of the memory modules, and the controller transmits a fully encoded chip-select signal group to each module. The buffers operate modally to correctly select ranks or partial ranks of memory devices on one or more modules for each transaction, depending on the mode.

    Abstract translation: 存储器控制器和存储器模块中的缓冲器各自以两种模式运行,这取决于控制器和模块通过其连接的主板的类型。 在第一模式中,控制器独立地向每个模块发送解码的芯片选择信号,并且主板数据信道使用到每个模块的多点连接。 在第二模式中,母板具有到每个存储器模块的点对点数据信道和命令地址连接,并且控制器向每个模块发送完全编码的芯片选择信号组。 缓冲器以模态方式进行操作,以根据模式正确选择每个事务的一个或多个模块上的存储器设备的等级或部分等级。
