With the ever increasing number of memories embedded in a System-on-Chip (SoC), power dissipation due to test has become a serious concern. This paper studies power dissipation in SRAMs and proposes a novel low power memory BIST. Its effectiveness is evaluated on memories in 130 and 90 nm technologies. As demonstrated, up to 30% power reduction can be achieved with virtually zero hardware overhead.
