Abstract :
In this paper, we report the results of a physical experiment aimed at assessing a new test method for CMOS SRAMs. The test method involves a new and simple philosophy for testing: monitor the switching behavior of a circuit rather than just the output logic state. Observing the dynamic (transient) power supply current can lead to drastic improvement in “real” defect coverage. We use the dynamic power supply current as indicative of such switching
