1. A memory system comprising:

  • a controller component to issue memory commands and communicate data via a controller interface; and

    memory modules, including a first memory module and a second memory module, each memory module having;

    a module data interface connected to the controller interface via point-to-point data connections to communicate a subset of the data;

    at least one delay-configurable data buffer coupled to the module data interface to communicate the subset of the data;

    memory devices coupled to the at least one data buffer to store and convey the subset of the data;

    a command input port to receive the memory commands from the controller component;

    a command relay circuit coupled to the command port to convey the memory commands from the memory module; and

    command logic coupled to the command port to receive the memory commands from the controller, the command logic to issue commands to the memory devices responsive to the memory commands.
