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 use processors such as MCU (MicroControl 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 RISCMachines, RISC proces...

Abstract

The invention provides a data backup method based on a heterogeneous hybrid memory. The data backup method based on the heterogeneous hybrid memory comprises the steps: judging a memory application manner; if needing to utilize a non-volatile memory (NVM) to apply, backing up data in a memory application with an NVM sign to the NVM, thereby avoiding that data in a dynamic random access memory (DRAM) is re-backed up to a magnetic disk according to a conventional method; meanwhile, judging whether the memory application with the NVM sign is a first backup; if the memory application with the NVM sign is not the first backup, performing incremental backup on the data to the NVM, thereby avoiding repeated backup. Therefore, the data backup method based on the heterogeneous hybrid memory can fully exert the advantages of the heterogeneous hybrid memory, avoids a repeated backup operation and improves data backup efficiency. Furthermore, the invention provides a data backup system based on the heterogeneous hybrid memory.

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 memory medium (Non-VolatileMemory, NVM) technology represented by resistance memory, ferroelectric memory, phase change memory, etc., the boundary between traditional memory and storage has gradually become blurred. The development of storage technology has 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 to introduce new indust...
