Abstract: An approach for creating a buried local interconnect around a DDB (double diffusion break) to reduce parasitic capacitance on a semiconductor device is disclosed. The approach utilizes a metal, as the local interconnect, buried in a cavity around the DDB region of a semiconductor substrate. The metal is disposed by two dielectric layers and the substrate.

The buried local interconnect is recessed into the cavity where the top surface of the interconnect is situated below the top surface of the surrounding S/D (source/drain) epi (epitaxy). The metal of the local interconnect can be made from W, Ru or Co.

Abstract: In some embodiments, a method receives a request for a video and receives a ranking of content delivery networks for the request. Also, global constraints are received for the content delivery networks. The global constraints define an allocation for respective content delivery networks. The method selects a content delivery network using the global constraints and the ranking. A score for the content delivery network is altered from a first score to a second score in the ranking and used in the selecting of the content delivery network. The content delivery network that is selected for the request is outputted.

Abstract: Methods and systems disclosed herein describe obfuscating plaintext cryptographic material stored in memory. A random location in an obfuscation buffer may be selected for each byte of the plaintext cryptographic material. The location of each byte of the plaintext cryptographic material may be stored in a position tracking buffer. To recover the scrambled plaintext cryptographic material, the location of each byte of the plaintext cryptographic material may be read from the position tracking buffer. Each byte of the plaintext cryptographic material may then be read from the obfuscation buffer and written to a temporary buffer. When each byte of the plaintext cryptographic material is recovered, the plaintext cryptographic material may be used to perform one or more cryptographic operations. The scrambling techniques described herein reduce the likelihood of a malicious user recovering plaintext cryptographic material while stored in memory.
