Abstract:

The integrated chips uses the millions of flip flops as a storing device. With continuous scaling deep into the sub-nm region the amount of charge which holds the data has decreased to the point where faults such as metastability occurs in IC have become a dominant failure mechanism which may corruption of the stored data. Metastability is an incident where the bi-stable element such as flip-flop goes in an unwanted state in which the output is at an midway level between binary logic “0” and binary logic “1.” With time any bi-stable element will resolve, however the time allowed for synchronization of digital data paths must be small to retain system performance.
