BICS-Based March Test for Resistive-Open Defects Detection in SRAM

Abstract:
Nowadays, embedded Static Random Memories (SRAMs) can occupy a significant portion of the chip area and contain hundreds of millions of transistors. Due to technology scaling, SRAM functional fault models, traditionally applied in memory testing, have become insufficient to correctly reproduce the effects produced by some defects generated during the manufacturing process. In this seminar, we investigate the possibility to use Built-In Current Sensors (BICSs) in combination with an optimized March algorithm to detect static faults associated to resistive-open defects. Experimental results obtained throughout electrical simulations validate the proposed technique demonstrating its viability and effectiveness.

The HUB Winter Meeting aims at bringing together researchers and administrators from the 5 INESC institutes, affiliated higher education institutions in Portugal and abroad, with key European and global players, to:
– Discuss key research and innovation issues at EU level.
– Inform institutional policy and strategy.
– Exchange best-practices about R&I management, career development and policy positioning.
– Promote, discuss and deliver vision, visibility, networking and impactful communication.
– Create, identify and deepen partnerships and collaboration opportunities for collaborative R&I.
