Patent ID: 8750061

Claim:
A computer system comprising: a central processing unit (CPU); a board; at least a first memory chip and a second memory chip mounted on the board; an electrical-optical signal converting unit configured to: receive a plurality of electrical signals from the CPU including at least a clock signal, control signals, and data signals, and convert each of the clock signal, the control signals, and the data signals into respective optical signals, and output the clock signal, the control signals, and the data signals as an optical clock signal, optical control signals, and optical data signals respectively; a plurality of optical conduits, each optical conduit configured to transmit a respective optical signal output from the electrical-optical signal converting unit; an optical signal splitting unit configured to: receive the optical signals transmitted by the plurality of optical conduits, split the optical clock signal into signals, split each of the optical control signals into signals, and split each of the optical data signals into signals; and an optical-electrical signal converting unit configured to: receive each of the split optical clock signals, receive each of the split optical control signals, receive each of the split optical data signals, convert the received split optical clock signal, split optical control signals, and split optical data signals into converted electrical signals, and output a first set of signals of the converted electrical signals to the first memory chip and output a second set of signals of the converted electrical signals to the second memory chip at the same time, wherein the memory chips do not comprise any components included in said optical-electrical signal converting unit.
