Fuzzy testing a software system
The disclosure is directed to a method, system and a computer readable medium of fuzzy testing a software system, using a grey-box fuzzy testing framework that optimizes the vulnerability exposure process while addressing security testing challenges. The grey-box fuzzy testing framework, unlike white-box testing, provides a focused and efficient assessment of a software system without analyzing each line of code. The disclosed embodiments provide a robust security mechanism that accumulates information about the system without increasing testing complexity, enabling fast and efficient security testing. The disclosed embodiments use security vulnerability metrics designed to identify vulnerable components in the software systems and ensures thorough testing of these components by assigning weights. A mutation engine may perform small data type mutations at the input's high-level design. The grey-box approach addresses three testing challenges: the system's complexity and size by avoiding intensive code analysis, outsourcing by limiting the knowledge about the system, and input and output fluctuation by creating a massive number of inputs. |

Unified test automation system
An automated testing framework to coordinate functions among code management, build management, automated test, resource reservation, artifact repositories and team communication subsystems. In one embodiment specific to software development, software developers check new code into a code management subsystem, a development project tracking system, or other tools that automatically generate a build. Test suites are then automatically selected and executed based on a scope of the project or code that was built. This scope can include such attributes as what portion of the software was built, the purpose (objective) of the build, the maturity of developing that build, and so forth. In one implementation, label directives may be used to associate build scope to test suites. During or after the automated tests, other actions may then be automatically triggered, to store test results, inform the development team, stored data integrated with test definition and results, or update an artifact repository. |

Plasma enhanced chemical vapor deposition of films for improved vertical etch performance in 3D NAND memory devices
The present disclosure generally relate to thin films incorporating high aspect ratio feature definitions and methods for forming the same. As gate height increases, 3D NAND gate stacks are subject to higher aspect ratio etching.

The inventors have devised a unique deposition scheme that compensates for etch performance degradation in deep trenches by a novel plasma-enhanced chemical vapor deposition (PECVD) film deposition method. The inventors have found that by grading various properties (e.g., refractive index, stress of the film, dopant concentration in the film) of the as-deposited films (e.g., silicon nitride) a more uniform etch profile can be achieved by compensating for variations in both dry and wet etch rates. |
