摘要:
A first pseudo random number generating circuit sequentially provides an output signal to a matching detecting circuit in response to a clock signal. A second pseudo random number generating circuit generates an initial value, and then, sequentially provides an output signal to a storage device in response to an output signal from the matching detecting circuit and the clock signal. Data with the output signal as an address is provided as an output signal from the storage device. When the matching detecting circuit detects matching between the output signals, the matching detecting circuit provides the output signals to the second pseudo random number generating circuit and an AND logic circuit. As described above, when the output signal of the matching detecting circuit is provided, the output signals from the storage device are provided as respective output control signals.
