Embodiment
Below, with reference to accompanying drawing, describe in detail according to the setting device of the embodiment of the present invention and method, the nonvolatile memory that comprises this setting device and electronic equipment.
Before starting description of the invention, first simply introduce the feature of nonvolatile memory.
As well known to the skilled person, will lose the content of storage after there is power-off in current, upper, while once starting, all contents need to be reloaded.At present, that the internal memory generally using all adopts is dynamic randon access technology (DRAM), as SDRAM, DDR and DDR II, all belongs to this internal memory.Having used an important feature of the internal memory of DRAM technology is exactly that they belong to volatile ram, once that is to say power-off, the data of its inside will disappear.In other words, why the data of DRAM internal memory the inside can exist, and are actually to rely on constantly power supply to refresh just to be kept.
Development along with storage medium technology, there is non-volatile internal memory, its technology comprises phase change memory technology (PCM, Phase Change, Memory), resistance internal memory (Magnetoresistive Random Access Memory, MRAM), ferroelectric memory (FeRAM) etc., after its basic characteristics are data writing, if do not change related physical condition, so just will keep data always.
This feature is very favourable for quick startup, because data still remain in internal memory after power-off, so do not need data to be re-loaded in internal memory while once starting upper, but the data that retain before can directly using were so just save data time of write memory again.
But this feature is disadvantageous for some special circumstances.For example at computing equipment, be subjected to occur in malice virus attack or program operation process when abnormal, need to restart machine.When using volatile memory as internal memory, restart machine by the data of removing in internal memory, therefore can guarantee does not have maliciously or abnormality code in internal memory.But after using nonvolatile memory as internal memory, even if restart, malice or abnormality code still remain in internal memory, cause removing malice or abnormality code.
