Memory pass-band signaling

A memory system comprising:

• a controller having a plurality of frequency translation circuits coupled to conductors external to the controller to up-convert data signals to a plurality of pass-bands;
• and
• a plurality of memory devices coupled to the conductors external to the controller, each of the plurality of memory devices including frequency translation circuits to down-convert the data signals from at least one of the plurality of pass-bands.

An electronic system comprising:

• a processor;
• and
• a memory system coupled to the processor, the memory system including a controller and a plurality of memory devices, each of the controller and the plurality of memory devices including frequency translation circuitry to allow each of the plurality of memory devices to simultaneously communicate with the controller.
