    摘要： 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.

    摘要： A memory controller writes to a virtual address associated with data residing within an asymmetric memory component of main memory that is within a computer system and that has a symmetric memory component, while preserving proximate other data residing within the asymmetric memory component. The symmetric memory component within the main memory of the computer system is configured to enable random access write operations in which an address within a block of the symmetric memory component is written without affecting the availability of other addresses within the block of the symmetric memory component during the writing of that address. The asymmetric memory component is configured to enable block write operations in which writing to an address within a region of the asymmetric memory component affects the availability of other addresses within the region of the asymmetric memory component during the block write operations involving the address.
