Patent ID: 7254331

Claim:
A memory hub for selectively communicating data between a system and a plurality of associated system memory devices communicably coupled with the memory hub, the memory hub comprising: a hub control unit, the hub control unit receiving incoming control signals, address signals, and data write signals and operable to route a memory control signal, a memory address signal, and a memory data write signal to at least one of the associated memory devices based on the contents of the control signal, the address signal, and the data signal, the memory transceiver being further operable to receive data read signals from the associated memory devices and relay the data read information to the system, and a multiple bit optical transceiver coupled with the hub control unit, the multiple but optical transceiver comprising: a light emitting device comprising: a plurality of light emitting diodes subsisting on a common bond pad each of the light emitting diodes operable to generate light in a particular range of wavelengths upon being electrically stimulated; the multiple bit optical transceiver operable to communicate multiple bit optical signals comprising a plurality of wavelengths of light, combinations of the plurality of wavelengths of light representing a combination of data bits in each transmission pulse, the multiple bit optical transceiver further operable to decode an incoming multiple bit optical signal into incoming electrical signals understandable by the hub control unit, and further operable to encode outgoing electrical signals into an outgoing multiple bit optical signal.
