  • Patent number: 9836409
    Abstract: A command from an application is received to access a data structure associated with one or more virtual addresses mapped to main memory. A first subset of the virtual addresses for the data structure having constituent addresses that are mapped to the symmetric memory components and a second subset of the virtual addresses for the data structure having constituent addresses that are mapped to the asymmetric memory components are identified. Data associated with the virtual address from the first physical addresses and data associated with the virtual addresses from the second physical addresses are accessed. The data associated with the symmetric and asymmetric memory components is accessed by the application without providing the application with an indication of whether the data is accessed within the symmetric memory component or the asymmetric memory component.

  • Patent number: 9672158
    Abstract: Main memory is managed by receiving a command from an application to read data associated with a virtual address that is mapped to the main memory. A memory controller determines that the virtual address is mapped to one of the symmetric memory components of the main memory, and accesses memory use characteristics indicating how the data associated with the virtual address has been accessed, The memory controller determines that the data associated with the virtual address has access characteristics suited to an asymmetric memory component of the main memory and loads the data associated with the virtual address to the asymmetric memory component of the main memory. After the loading and using the memory management unit, a command is received from the application to read the data associated with the virtual address, and the data associated with the virtual address is retrieved from the asymmetric memory component.

  • Patent number: 9514038
    Abstract: A memory controller (MC) is associated with a remapping table to enable access to content in a memory system that includes asymmetric memory. The MC receives a request for a memory read or an Input/Output (I/O) write from a central processing unit (CPU) for a physical address specified by the system's memory management unit (MMU). The CPU uses the MMU to manage memory operations for the CPU, by translating the virtual addresses associated with CPU instructions into physical addresses representing system memory or I/O locations. The MC for asymmetric memories is configured to process the MMU-specified physical addresses as an additional type of virtual addresses, creating a layer of abstraction between the physical address specified by the MMU and the physical memory address with which that address is associated by the MC. The MC shields the CPU from the computational complexities required to implement a memory system with asymmetric components.

  • Patent number: 9513695
    Abstract: In one embodiment of the invention, a memory apparatus is disclosed. The memory apparatus includes a memory array, a block read/write controller, and a random access read memory controller. The memory array is block read/write accessible and random read accessible. The block read/write controller is coupled between the memory array and an external interconnect. The block read/write controller performs block read/write operations upon the memory array to access blocks of consecutive memory locations therein. The random access read memory controller is coupled between the memory array and the external interconnect in parallel with the block read/write access controller. The random access read memory controller performs random read memory operations upon the memory array to access random memory locations therein.

  • Patent number: 9223719
    Abstract: Data stored within symmetric and asymmetric memory components of main memory is integrated by identifying a first data as having access characteristics suitable for storing in an asymmetric memory component. The first data is included among a collection of data to be written to the asymmetric memory component. An amount of data is identified within the collection of data to be written to the asymmetric memory component. The amount of data is compared within the collection of data to a volume threshold to determine whether a block write to the asymmetric memory component is justified by the amount of data. If justified, the collection of data is loaded to the asymmetric memory component.
