  • Patent number: 9639463
    Abstract: The various implementations described herein include systems, methods and/or devices used to enable heuristic aware garbage collection in storage systems (e.g., non-volatile data storage systems using one or more flash memory devices). In one aspect, a time parameter (e.g., dwell time) and/or heuristics (e.g., error count, error rate, number of reads, number of times programmed, etc.) are used in a garbage collection scheme. For example, in some implementations, the method of garbage collection for a storage medium in a storage system includes (1) determining a time parameter for a block in the storage medium, and (2) in accordance with a determination that the time parameter for the block is greater than a first threshold time, enabling garbage collection of the block.

  • Patent number: 9441114
    Abstract: A bond coating having high corrosion and oxidation resistance and good compatibility with a thermal barrier coating is disclosed. The bond coating may be an optimized NiCrAlY material with additional materials that eliminates the presence of beta phase for oxidation by replacing the beta phase with a gamma/gamma prime system. The bond coating may also decrease the presence of phases that are detrimental to the mechanical and oxidation properties of the system, such as the sigma and BCC chromium phases. The bond coating may also have a gamma/gamma prime transition temperature that is about 400 degrees Celsius higher than conventional bond coatings, which enables local stresses to be reduced.
