摘要： A semiconductor memory system includes a memory controller and a memory. The memory controller includes a control signal converting unit converting a control signal into a converted control signal including n sequential clock pulses and a target clock pulse activated after a time period has elapsed from a start point of the n sequential clock pulses, and output the converted clock signal, and a controller transmitting unit converting the converted control signal into an optical signal, and transmitting the optical signal to the memory. The memory includes a memory receiving unit converting the optical signal into an electrical signal, and a control signal re-converting unit detecting the time period from the electrical signal, and converting the control signal into a control signal corresponding to the time period.
