  • System and method for providing kernel intrusion prevention and notification
    Patent number: 9703725
    Abstract: A memory protection module includes comparison logic that has a write-once window CSR that stores a memory address range, and window protection logic. The comparison logic receives a memory write transaction, determines a memory address of the memory write transaction, and provides an indication as to whether or not the memory address is included in the memory address range. The window protection logic receives the memory transaction, receives the indication from the comparison logic, allows the memory write transaction to proceed in response to the indication indicating that the memory address is not included in the memory address range, and drops the memory write transaction in response to the indication indicating that the memory address is included in the memory address range.

  • Systems and methods for support of non-volatile memory on a DDR memory channel
    Patent number: 9645746
    Abstract: Systems and methods are provided for supporting use of non-volatile memory (NVM) on a double data rate (DDR) memory channel for an information handling system so that non-volatile memory devices (e.g., such as Phase Change Memory “PCM” devices) may be employed for main memory usage. In one possible implementation, information handling system memory reads may be managed directly in hardware as memory semantics via use code, while memory writes may be separately handled, e.g., via an operating system (OS)/driver. In another possible implementation, both DRAM-based and NVM-based memory systems may be populated for an information handling system.
