  • Patent number: 11074189
    Abstract: Various embodiments are provided for providing byte granularity accessibility of memory in a unified memory-storage hierarchy in a computing system by a processor. A location of one or more secondary memory medium pages in a secondary memory medium may be mapped into an address space of a primary memory medium to extend a memory-storage hierarchy of the secondary memory medium. The one or more secondary memory medium pages may be promoted from the secondary memory medium to the primary memory medium. The primary memory medium functions as a cache to provide byte level accessibility to the one or more primary memory medium pages. A memory request for the secondary memory medium page may be redirected using a promotion look-aside buffer (“PLB”) in a host bridge associated with the primary memory medium and the secondary memory medium.

  • Publication number: 20210209047
    Abstract: A system includes a printed circuit board (PCB) on which is disposed memory components and a processor disposed on the PCB and coupled between the memory components and a host memory controller. The processor comprises a memory channel network (MCN) memory controller to handle memory requests associated with the memory components; a local buffer; and a core coupled to the MCN memory controller and the local buffer. The core executes an operating system (OS) running a network software layer and a distributed computing framework; and an MCN driver to: receive a network packet from the network software layer; store the network packet in the local buffer; and assert a transmit polling field of the local buffer to signal to the host memory controller that the network packet is available for transmission to a host computing device.
