Abstract

The invention discloses a fusion memory system of a nonvolatile memory and a dynamic random access memory. The nonvolatile memory and the dynamic random access memory are fused together and are jointly used as a memory of a computer system for unified management, the dynamic random access memory can carry out unified addressing together with the nonvolatile memory, part capacity of the dynamic random access memory can be used as a high-speed cache of the nonvolatile memory, the capacity of cache space adapts to data load characteristics by itself and is dynamically matched, so that the access speed of the nonvolatile memory is improved, access frequency of a disk by an I / O can be lowered, and the overall performance of the computer system is improved.

Description

technical field [0001] The invention belongs to the field of computer storage, and in particular relates to a fusion memory system of a nonvolatile memory and a dynamic random access memory. Background technique [0002] The emergence of a new type of non-volatile memory (Non-Volatile Memory, NVM) provides a new way to expand computer memory, and at the same time promotes changes in the computer system structure. The existing NVM includes PCM (Phase Change Memory, phase change memory), STT-RAM (Spin Transfer Torque Random Access Memory, spin transfer torque random access memory), MRAM (Magnetic Random Access Memory, magnetic random access memory), FeRAM ( Ferroelectric Random Access Memory, ferroelectric random access memory), etc. The storage mechanism of the new non-volatile memory is no longer the traditional charge flow formed by electrons to store data, but the use of magnetoresistance effect, resistance change effect, phase change effect and other mechanisms to achiev...
