Abstract: A memory core of a semiconductor data storing circuit device in a semiconductor chip is composed of a memory cell array having memory cells of rows and columns, data input/output circuits of a normal operation in which a data input line and a data output line for one bit of data are arranged at every four columns of the memory cell array, and checking circuits of a test operation in which a test data input line and a test data output line for one bit of test data are arranged at every eight (or two) columns of the memory cell array.

Abstract: In the WDM systems, the OSNR and the signal loss among the optical signals are substantially minimized at the receiving terminal to combat the SRS effects. An equal amount of the signal loss is expected for every span in the transmission path so that the optical amplifier gain tilt is not affected among a number of wavelength frequencies in the optical signal. This is accomplished by controlling the amplification process according to a feedback from the monitoring units for monitoring the optical signal.

Abstract: Optical signal transmission is improved by reducing the variance in light output level and OSNR by adjusting optical signal intensity and gain tilt, taking SRS influence into consideration.
