1. A configurable memory module supporting a first configuration and a second configuration, the configurable memory module comprising:
a first module command port to receive module commands external to the configurable memory module in the first configuration and the second configuration;
a command relay coupled to the first module command port to impose a relay delay on the module commands and convey the module commands as first delayed module commands;
a second module command port coupled to the command relay to convey the first delayed module commands from the configurable memory module;
a selectable delay element coupled to the first module command port and conveying the module commands as second delayed module commands, the selectable delay element imposing an additional delay of the relay delay on the second delayed module commands in the first configuration as compared with the second configuration; and
at least one memory device having a memory-device command port coupled to the selectable delay element to receive the second delayed module commands.
