    Abstract: A scan asynchronous memory element includes: an asynchronous memory element configured to receive an n-input; and a scan control logic circuit configured to generate an n-bit signal input and the n-input to the asynchronous memory element from a scan input. The scan control logic circuit outputs the signal input when a control signal supplied to the scan control logic circuit has a first bit pattern, the scan control logic circuit outputs the scan input when the control signal has a second bit pattern, and the scan control logic circuit outputs a bit pattern allowing the asynchronous memory element to hold a previous value when the control signal has a bit pattern other than the first and second bit patterns.
