Abstract: Embodiments disclosed include memory bitcell clusters employing localized generation of complementary bitlines to reduce memory area. The memory bitcell clusters disclosed may be static random access memory (SRAM) used as central processing unit (CPU) register files. The memory bitcell clusters disclosed include a plurality of memory bitcells that share a common bitline. To reduce area required to provide complementary bitlines for the memory bitcells, the memory bitcell clusters include a localized inverter circuit. The localized inverter circuit is configured to invert a common bitline localized to the memory bitcells to provide a complementary bitline for the memory bitcells in the memory bitcell cluster. Because the inverter circuit is localized to the memory bitcells, a track in a semiconductor die for the complementary bitline does not extend beyond the memory bitcell cluster, minimizing the complexity of the memory bitcell cluster by reducing a number of bitline tracks used by half.

Abstract: A method is provided in one example embodiment that includes detecting repetitive connections from a source node to a destination node, calculating a score for the source node based on the connections, and taking a policy action if the score exceeds a threshold score. In more particular embodiments, the repetitive connections use a hypertext transfer protocol and may include connections to a small number of unique domains, connections to small number of unique resources associated with the destination node, and/or a large number of connections to a resource in a domain. Moreover, heuristics may be used to score the source node and identify behavior indicative of a threat, such as a bot or other malware.
