Abstract:
1. An expansion memory system comprising: a first optical/electronic interface in electrical communication with a processor, the first optical/electronic interface configured to receive and convert optical signals into electronic signals that are sent to the processor and receive and convert electronic signals produced by the processor into optical signals; a memory expansion board comprising memory, an optical fan-in bus and an optical fan-out bus; and a second optical/electronic interface attached to the memory expansion board, the second optical/electronic interface configured to receive and convert optical signals into electronic signals that are sent to the memory and receive and convert electronic signals corresponding to information stored in the memory into optical signals, wherein the optical signals produced by the first optical/electronic interface are sent to the second optical/electronic interface via the optical fan-in bus and the optical signal produced by the second optical/electronic interface are sent to the first optical/electronic interface via the optical fan-out bus.
