  • Publication number: 20230022027
    Abstract: Row-level security (RLS) may provide fine-grained access control based on flexible, user-defined access policies to databases, tables, objects, and other data structures. A RLS policy may be an entity or object that defines rules for row access. A RLS policy may be decoupled or independent from any specific table. This allows more robust and flexible control. A RLS policy may then be attached to one or more tables. The RLS policy may include a Boolean-valued expression.

  • Publication number: 20230011150
    Abstract: A command to read specific data stored at a memory die is received. A read operation is performed while operating both a memory controller and the memory die simultaneously at a first frequency. A processor determines whether a first error rate associated with the memory die satisfies a first error threshold criterion (e.g., UECC). Responsive to determining that the first error rate satisfies the first error threshold criterion, the read operation is repeated while operating at least one of the memory controller or the memory die at a second frequency that is different from the first frequency. The processor determines whether a second error rate associated with the memory die satisfies a second error threshold criterion. Responsive to determining that the second error rate satisfies the second error threshold criterion (e.g. UECC persists), determining that the read operation has failed.
