Embodiment Construction

[0043] Such as figure 1 Shown is a block diagram of a heterogeneous hybrid memory.

[0044] The heterogeneous hybrid memory adopts the same physical connection method as the DDR3 interface circuit. The heterogeneous hybrid memory is inserted into the commonly used DDR3 interface circuit for use. The address (Addr), command (Cmd) and data transmitted by the operating system to the heterogeneous hybrid memory Information such as (Data) is input to the controller (Controller) through the interface circuit, and the controller (Controller) controls the access and control of the conventional memory DRAM and the non-volatile storage medium NVM through the received data and internal logic. Among them, the controller (Controller) can adopt MCU (Micro Control Unit, micro control unit), FPGA (Field Programmable Gate Array, field programmable gate array), CPLD (Complex Programmable Logic Device, complex programmable logic device) and ARM (Advanced RISC Machines , RISC processor) and othe...

Abstract

The data backup method based on heterogeneous hybrid memory judges the way of memory application. If NVM memory application needs to be used, the data in the memory application with NVM mark is backed up to NVM. Thereby, it is avoided to back up the data in the DRAM to the disk in the conventional method again. At the same time, it is judged whether the memory application with the NVM flag is the first backup, and if not, it is incrementally backed up to the NVM. Ability to avoid duplicate backups. Therefore, the above-mentioned data backup system based on heterogeneous hybrid memory can give full play to the advantages of heterogeneous hybrid memory, avoid repeated backup operations, and improve data backup efficiency. In addition, a data backup system based on heterogeneous hybrid memory is also provided.

Description

technical field [0001] The invention relates to data backup technology, in particular to a highly efficient data backup method and system based on heterogeneous hybrid memory. Background technique [0002] With the development of emerging non-volatile random storage medium (Non-Volatile Memory, NVM) technology represented by resistive memory, ferroelectric memory, phase change memory, etc., the boundary between traditional memory and storage has gradually become blurred. It has promoted the development of storage technology and laid a good foundation for the emergence of new memory and storage architectures. [0003] By combining the new NVM and DRAM (Dynamic Random Access Memory, dynamic random access memory), a hybrid memory architecture is built to form a heterogeneous hybrid memory. Heterogeneous hybrid memory has the characteristics of NVM and DRAM at the same time, which meets the conventional memory interface of existing industrial control equipment, without the need...
