摘要:
A phase change memory comprises a first electrode formed over a substrate, a patterned phase change material layer formed over the first electrode to contact the first electrode and including a conductive material, and a second electrode formed over the patterned phase change material layer to contact the patterned phase change material layer. Instead of heat generation, the conductive channel is used to adjust resistance while maintaining characteristics of non-volatile memories. Hence, the power consumption can be reduced. Due to no use of the phase change, the shortened lifetime of equipment for fabricating semiconductor memories, usually caused by a volume change during the phase change, can be reduced.

An optical transceiver case is provided. The optical transceiver case has an optical transmission/reception device and a PCB that operates the optical transmission/reception device. The optical transceiver case includes a lower plate and an upper plate. The lower plate supports the optical transmission/reception device and the printed circuit board, and includes handle grooves formed on both external sides of the lower plate to allow the optical transceiver case to be mounted/detached to/from an optical transmission/reception system's board. The upper plate is coupled to the lower plate to mount the optical transmission/reception device and the printed circuit board, and includes a protuberance embossed on an external upper surface of the upper plate in order to discharge heat generated from the optical transmission/reception device and the PCB to the outside. The optical transceiver case is easily mounted detached to/from on optical transmission/reception system's board and maintains a constant internal temperature.

Provided are an optical code-division multiple-access (O-CDMA) network system and method and an optical encoder and decoder in the system. The O-CDMA network system includes a central station and at least one subscriber unit. In a code assigning method of the optical code-division multiple-access network system, first, the subscriber unit transmits a code assignment request signal to the central station. Then, the central station assigns a code to the subscriber unit. Thereafter, the subscriber unit programs an encoding and decoding code based on the assigned code. The optical encoder and decoder includes a refraction grating, arrayed optical waveguides, optical switches, and optical reflectors. Therefore, a central code assignment scheme can be achieved, and programming of the encoder and decoder is possible.
