Memory data protection method, device and circuit

Abstract

The embodiment of the invention provides a memory data protection method, device and circuit, which can store a large amount of data stored in a volatile memory of a server into a nonvolatile memory on the conditions that the CPU of the server is not utilized, and the CPU of the server cannot work normally with the ultra-low power consumption. The method comprises the steps that whether the CPU of the server works normally or not is detected; and when it is detected that the CPU of the server cannot work normally, a low-power-consumption processor is used for carrying the data from the servermemory to the nonvolatile memory according to a preset carrying rule.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method, device and circuit for protecting memory data. Background technique [0002] With the development of computer technology, the memory capacity of servers in various fields is getting larger and larger, and they are all volatile storage. Most of the memory capacity is above 100G, and some even exceed 256G. A large amount of data is stored in these large-capacity, volatile memories. In the case of abnormal shutdown of the server or sudden power failure, the data stored in the large-capacity memory will be lost. If important data is not written to the hard disk, the impact will be even greater. [0003] Most of the memory data protection schemes in the prior art are based on the following two methods: [0004] Use battery power to save data: add a battery power supply module to the existing server memory power supply unit. In the case of abnormal shutdown or power fail...
