    • Because a bypass circuit BP connected in parallel with serial paths of first and second storage circuits MF and SF has less serially-connected stages of gates incorporated therein than the storage circuits and has shorter information transfer delay of input data to an output terminal 21 than the storage circuits, the bypass circuit BP outputs the information to the output terminal before the outputs of the storage circuits are determined when data supplied to a data input terminal 20 is fetched synchronously with a clock signal CK. The first and second storage circuits MF and SF are master/slave-operated in diagnosis mode, and the output operation of the bypass circuit BP is inhibited according to the states of signals C1 and C2 for controlling their master/slave operations regardless of the clock change of the first control signal CK. Thus, the master/slave operations of the first and second storage circuits MF and SF are assured in the diagnosis mode.
    • 因为与第一和第二存储电路MF和SF的串行路径并联连接的旁路电路BP与存储电路并入的门的串联级较少,并且输入数据的信息传输延迟比输出端21更短 存储电路时,在与时钟信号CK同步地取出提供给数据输入端子20的数据之前,在确定存储电路的输出之前,旁路电路BP将该信息输出到输出端子。 第一和第二存储电路MF和SF在诊断模式下被主/从操作,并且根据用于控制其主/从操作的信号C1和C2的状态来禁止旁路电路BP的输出操作,而不管时钟 改变第一控制信号CK。 因此,在诊断模式中确保第一和第二存储电路MF和SF的主/从操作。

    • When signal transmission is performed between two semiconductor integrated circuit devices in synchronization with a clock signal using a small signal amplitude relative to an operating voltage of the two semiconductor integrated circuit devices, a received signal is held in the receiving semiconductor integrated circuit device in synchronization with the clock signal while the small signal amplitude of the held signal is kept substantially without change. The received signal having the small signal amplitude is amplified along a signal transmission path including a combined logic circuit to a subsequent latch circuit of the receiving semiconductor integrated circuit device.
