Previous works have shown that the traditional implementations of power management (i.e., using power gating or voltage scaling) can also mitigate the aging effect induced by Negative Bias Temperature Instability (NBTI), due to the partial recovery that occurs during the idle intervals used by power management. However, such a potential has been exploited only partially because of the different nature...
Partitioning a memory into multiple blocks that can be independently accessed is a widely used technique to reduce its dynamic power. For embedded systems, its benefits can be even pushed further by properly matching the partition to the memory access patterns. When leakage energy comes into play, however, idle memory blocks must be put into a proper low-leakage sleep state to actually save energy...
Row-based power-gating has recently emerged as a meet-in-the-middle sleep transistor insertion paradigm between cell-level and block-level granularity, in which each layout row defines the unit of gating, and different rows can be clustered and share the same sleep transistor. Previous works, however, assume the availability of a single virtual ground voltage, thus making the decision of whether to...
