    • Each of first and second program circuits includes a determination node, first to fourth fuses, first to fourth N channel MOS transistors, and first to fourth supply lines. The first to fourth N channel MOS transistors receive first to fourth row address predecode signals, respectively. The first N channel MOS transistor included in the first program circuit and the first N channel MOS transistor included in the second program circuit are arranged adjacent to each other. The first supply line provides a first row address predecode signal to the gate of these two N channel MOS transistors. The same applies for the second to fourth N channel MOS transistors and the second to fourth supply lines. Accordingly, the interconnection capacitance of the row address predecode signal line can be reduced. Also, the size of the transistor driving the row address predecode signal and the transistors in the program circuit can be reduced to allow a smaller layout area for the entire chip.
    • 第一和第二编程电路中的每一个包括确定节点,第一至第四保险丝,第一至第四N沟道MOS晶体管和第一至第四电源线。 第一至第四N沟道MOS晶体管分别接收第一至第四行地址预解码信号。 包括在第一编程电路中的第一N沟道MOS晶体管和包括在第二编程电路中的第一N沟道MOS晶体管彼此相邻布置。 第一电源线为这两个N沟道MOS晶体管的栅极提供第一行地址预解码信号。 同样适用于第二至第四N沟道MOS晶体管和第二至第四供电线。 因此,可以减少行地址预解码信号线的互连电容。 此外,可以减小驱动行地址预解码信号的晶体管的尺寸和程序电路中的晶体管的尺寸,以允许整个芯片的布局面积较小。

    • A clock signal, which is generated by utilizing a delay circuit having a delay time depending on the operation frequency of an internal clock signal, is applied to a first circuit for activation thereof, and a clock signal, which has a fixed delay not dependent on the clock frequency and is adjusted in phase with respect to an external clock signal, is applied to a second circuit receiving the output signal of the first circuit for operation thereof. Thus, the operation timing of the second circuit can be set to be as late as possible. Consequently, it is possible to mitigate the operation conditions of the first circuit, to achieve a high speed data transfer. Even in the high speed operation, internal data can be reliably taken in, and transferred accurately.
    • 通过利用具有取决于内部时钟信号的工作频率的延迟时间的延迟电路产生的时钟信号被施加到第一电路以激活它,以及时钟信号,其具有不依赖于 时钟频率并相对于外部时钟信号被同相调节,被施加到接收第一电路的输出信号以用于其操作的第二电路。 因此,可以将第二电路的操作定时设置为尽可能晚。 因此,可以减轻第一电路的操作条件,以实现高速数据传输。 即使在高速运行中,内部数据也可以被可靠地接收并准确传送。

    • In an image processing apparatus for creating synthetic image information by embedding sub-information in an invisible state in main image information in a visible state, attention pixels in the main image information are set, a specific pixel block is created by assigning a first specific pixel to the attention pixel of a first color and a second specific pixel to the attention pixel of a second color, first key information is selected for a first value of the sub-information constituted by binary information and second key information is selected for a second value, color difference modulation processing is performed on the selected key information based on a predetermined color difference amount, and the color-difference-modulated key information is superposed on the specific pixel block to thereby create the synthetic image information in which the sub-information in an invisible state is embedded in the main image information.
