  • Publication number: 20110289293
    Abstract: There is provided a semiconductor device which is simple in configuration and resistant to tampering. A user input unit receives an authentication code input by a user. A CPU determines whether a user's access is legal based on the input authentication code and activates an enable signal if the user's access is legal. A normal row decoder decodes the row address specified by the CPU and selects a normal memory cell of any row based on the result of decode. A redundancy row decoder prohibits the selection by the normal row decoder when the specified row address agrees with the row address of a predetermined normal memory cell only if the enable signal is activated and selects a redundant memory cell of any row.

  • Patent number: 7536110
    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.
