Embodiment Construction

[0029] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0030] Generally speaking, the present invention is mainly based on two points:

[0031] One is the hardware construction based on PCM non-volatile memory, which mainly includes front-end protocol conversion functional parts and back-end PCM control functional parts. The front-end protocol conversion function part analyzes the read and write command requests in the memory interface and puts them into the request queue to be processed at the back-end. The back-end PCM control function part is mainly used to process the commands parsed in the front-end module, and generate the hardware control logic of the non-volatile memory device through the internal state machine.

[0032] The second is to add software support for PCM non-volatile memory in the host memory management module, so that the host can use the PCM non-volatile memory. The main...

Abstract

The invention discloses a nonvolatile memory system and a management method of the nonvolatile memory system. A nonvolatile memory is constructed by adopting a nonvolatile PCM storage device, management on the nonvolatile memory is added to a host memory management module, unified management on the nonvolatile memory and a traditional DRAM is achieved, and the nonvolatile memory and the traditional DRAM can be fused to form a unified memory for the access of a host processor. According to the nonvolatile memory system and the management method of the nonvolatile memory system, the problem that power failure data of the traditional DRAM are lost and the problem of data consistency can be solved, and meanwhile energy consumption of the host memory can be lowered.

Description

technical field [0001] The invention belongs to the field of computer data storage, and in particular relates to a non-volatile memory system and a management method thereof. Background technique [0002] The memory of the host computer has always been an important part of the computer system, and it is an important component that determines the performance of the system. Traditional memory has always been composed of Dynamic Random Access Memory (DRAM). DRAM has experienced four generations of evolution from its development to the present. From the initial single-rate synchronous dynamic random access memory SDR DRAM, with the development of technology, the first generation of DDR (Double Data Rate) DRAM appeared. Data is transmitted along the edge, and then the second and third generation products were launched, namely DDR2DRAM and DDR3DRAM technology. Although their design is very similar to the previous one, they can get faster clock speed and higher data. The transmi...
