Efficient testing of SRAM with optimized march sequences and a novel DFT technique for emerging failures due to process variations.

Efficient testing of SRAM with optimized march sequences and a novel DFT technique for emerging failures due to process variations.

With increasing inter-die and intra-die parameter variations in sub-100-nm process technologies, new failure mechanisms are emerging in CMOS circuits. These failures lead to reduction in reliability of circuits, especially the area-constrained SRAM cells. In this paper, we have analyzed the emerging...
