Abstract

The invention discloses a device for realizing volatile memory backup. The device for realizing volatile memory backup comprises a volatile memory, a non-volatile memory, a power supply switchover unit used for selecting an external power supply or an internal power supply to supply power, an internal power supply used for supplying power during extreme abnormal power-off, and a mixed memory control unit. By virtue of the technical scheme provided by the invention, backup for data in the volatile memory into the non-volatile memory is finished by using the mixed memory control unit during extreme abnormal power-off, thus preventing a plurality of modules from being coordinated and matched to finish the function, and then effectively lowing the complexity of design and debugging for volatile memory data backup, and greatly meeting market needs on volatile memory backup.

Description

technical field [0001] The invention relates to backup technology, in particular to a device for realizing backup of volatile memory when power is cut off extremely abnormally. Background technique [0002] As we all know, volatile memory chips such as synchronous dynamic random access memory (SDRAM) chips or memory sticks composed of a plurality of volatile memory chips (hereinafter collectively referred to as volatile memories) are widely used in personal computers, servers, In various network equipment and computing equipment and other equipment. Data stored in volatile memory is lost when power is lost. Especially when the external power supply and the backup external power supply of the equipment using volatile memory are stopped at the same time or the system of the equipment is abnormally restarted (hereinafter referred to as extreme abnormal power failure) in critical occasions, the volatile The unprocessed data stored in the memory is immediately lost, which will ...
