  • Semiconductor storage device having synchronous and asynchronous modes
    Patent number: 9618578
    Abstract: A method for performing scan testing using a scan chain having a plurality of storage elements is described. During a capture phase, each storage element of the scan chain stores data from a first data input of the storage element synchronously to a clock signal. And during a shift phase, a scan pattern is shifted into the scan chain in which each storage element stores data from a second data input of the storage element asynchronously with to the clock signal.
