Abstract:Embedded RAMs are RAMs, whose address, data, and read/write controls can not be directly controlled or observed through the chip's 1/0 pins. Testing these memories, which are incorporated on a large percentage of VLSI devices, is naturally harder because of the lack of controllability of its inputs and observability of its outputs. Testing such RAMs is the theme of this paper. It brings to light the challenges involved in testing embedded RAMs, and discusses techniques such as design for testability (DFT) and … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
