Abstract :
This paper presents the effectiveness of various stress conditions (mainly voltage and frequency) on detecting the resistive shorts and open defects in deep sub-micron embedded memories in an industrial environment. Simulation studies on very-low voltage, high voltage and at-speed testing show the need of the stress conditions for high quality products. The above test conditions have been validated to screen out the bad chips on real silicon (on a test-chip) built on CMOS 0.18 μm technology.
