Memory Semantic Fabric Data Access Management

The patent introduces a memory semantic fabric as an intermediary layer between the PCIe interface and the memory subsystem. This fabric includes a fabric switch and memory fabric protocol that translate standard PCIe operations into optimized memory access operations, thereby maintaining PCIe compatibility while significantly improving memory usage efficiency and data processing speed.

The memory semantic fabric is segmented into distinct functional components: a fabric switch for routing operations, memory fabric protocols for communication, and transient component management for access control. This segmentation allows the system to achieve high productivity while managing complexity through modular design, where each component has a specific function and can be independently configured and secured.

The patent implements dynamic access control in the memory semantic fabric where access permissions are not fixed but can be changed based on operational context. Transient components can be dynamically created, configured with specific access rights, and destroyed when no longer needed. This dynamic approach maintains operational flexibility while ensuring security through context-aware access control that limits exposure to only what is necessary at each moment.

The patent applies preliminary action by pre-configuring access control policies and permissions for transient components before they are activated in the memory semantic fabric. When a transient component is created, its access rights are predetermined and restricted to only the specific memory regions and operations it requires. This preliminary configuration of security parameters prevents vulnerabilities from arising in the first place, allowing versatile transient components to operate securely.
