Specific embodiment
In order to make those skilled in the art more fully understand application scheme, below in conjunction in the embodiment of the present application
Attached drawing, the technical scheme in the embodiment of the application is clearly and completely described, it is clear that described embodiment is only this
Apply for a part of the embodiment, instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art exist
Every other embodiment obtained under the premise of creative work is not made, shall fall in the protection scope of this application.
Referring to Fig. 1, which is a kind of flow chart of memory error detection method provided by the embodiments of the present application.
Memory error detection method provided in this embodiment includes the following steps:
S101: the error reporting of memory is obtained.
In the present embodiment, memory refers to equipment for storing data.Memory may include volatile memory
(volatile memory), such as random access memory (random-access memory, RAM)；Memory also can wrap
It includes nonvolatile memory (non-volatile memory), such as flash memory (flash memory), hard disk (hard
Disk drive, HDD) or solid state hard disk (solid-state drive, SSD)；Memory can also include depositing for mentioned kind
The combination of reservoir.
In the present embodiment, error reporting can obtain in real time from memory, and primary mistake occurs in memory, can produce
A raw corresponding error reporting.
In the present embodiment, error reporting can carry vicious type identification and time of origin.Wherein, the class of mistake
The type of mistake occurs for distinguishing memory for type mark；Time of origin is the time that corresponding mistake occurs.For example, it is assumed that storage
Device is hard disk, and medium mistake has occurred when 30 divide 20 seconds at 16；Firmware error has occurred when 20 divide 30 seconds at 18.So,
Two error reportings will be obtained at this time, wrong type identification is " media error " in first error reporting, when generation
Between be " 16:30:20 "；Wrong type identification is " firmware error " in second error reporting, and time of origin is
"18:20:30".For upper example only for convenience of understanding, the record form of type identification and time of origin is not limited to the form of example.
S102: add up what the mistake occurred within a preset period of time according to the type identification of the mistake and time of origin
Actual frequency.
In the present embodiment, the actual frequency that the mistake that can add up that there is same type to identify occurs, has inhomogeneity
The frequency of the mistake of type mark is with each other without accumulative.
The time span of the preset time period can be determining according to the type of memory and the type of mistake, different mistakes
There is corresponding preset time period, and the time span of preset time period is at the end of being carved at the beginning of preset time period
Time span between quarter.
The mode that actual frequency occurs within a preset period of time for three kinds of cumulative errors is described below.
Mode 1: at the beginning of determining that within a preset period of time actual frequency occurs for a certain moment as cumulative error, with
Preset time period is the time cycle, sequentially adds up the actual frequency that mistake occurs in each period.Mistake hair in each period
Raw actual frequency is individually accumulative since zero degree, i.e., for a certain selected preset time period, front and back two adjacent thereto
The reality that cumulative error occurs in the actual frequency and the selected preset time period that cumulative error occurs in a preset time period
Number is unrelated.In order to facilitate understanding, it is illustrated below:
Determine that 9:00:00 is at the beginning of within a preset period of time actual frequency occurs for cumulative error, it is assumed that when default
Between segment length be 1 hour.Then needing first accumulative time cycle is to terminate since 9:00:00 to 10:00:00；It needs
Second time cycle of accumulation is to terminate since 10:00:00 to 11:00:00, and so on, that is, add up in every 1 hour
The actual frequency that mistake occurs, and initial number accumulative every time is 0.
Mode 2: for the multiple mistakes identified with same type, one mistake of every generation, all by the generation of the mistake
At the beginning of moment is as a preset time period, the mistake successively added up in each preset time period occurs practical secondary
Number.It should be noted that multiple preset time periods corresponding to multiple mistakes might have and partly overlap, but multiple mistakes are corresponding
Preset time period in mistake occur the accumulative of actual frequency be independent of each other.In order to facilitate understanding, it is illustrated below:
Assuming that preset time segment length is 1 hour, the mistake type identification having the same of generation.First mistake occurs
Time be 9:00:00, using the generation moment of the mistake as a preset time period at the beginning of, then need to add up at this time
The actual frequency that mistake occurs in this preset time period from 9:00:00 to 10:00:00.Second mistake occurs in 9:30:
00, at the beginning of being needed at this time using the generation moment of the mistake as two preset time periods, i.e., need at this time accumulative from 9:
The actual frequency that mistake occurs in this preset time period of 30:00 to 10:30:00.It should be noted that in 9:30:00 to 10:
00:00 has had begun and actual frequency occurs to mistake in the corresponding preset time period of second mistake has added up, while to the
Mistake generation the accumulative of actual frequency is also carrying out in the corresponding preset time period of one mistake, the two mistakes are two corresponding
There is the part of overlapping between preset time period but influence is not present in the two accumulative processes from each other.
Mode 3: for the multiple mistakes identified with same type, using first wrong generation moment as first
At the beginning of preset time period, it is corresponding after accumulative in first preset time period to will occur in the preset time period
Finish time after first mistake the generation moment as second preset time period at the beginning of, and so on, according to
It is secondary to be added up.In order to facilitate understanding, it is illustrated below:
Preset time segment length is 1 hour, and the time that mistake occurs for the first time is 9:00:00, when by the generation of the mistake
At the beginning of carving as a preset time period, then accumulative this preset time from 9:00:00 to 10:00:00 is needed at this time
The actual frequency that mistake occurs in section.First mistake after finish time 10:00:00 occurs at this time should in 10:30:00
At the beginning of the generation moment of mistake is as second preset time period, i.e., need at this time accumulative from 10:30:00 to 11:30:
The actual frequency that mistake occurs in 00 this preset time period.After accumulative, then by the head after finish time 11:30:00
It is a mistake occur at the time of as third preset time period at the beginning of, and so on.
S103: if the actual frequency is greater than or equal to preset times, confirm that mistake occurs in the memory.
For above-mentioned Three models, add up the actual frequency that the mistake occurs in some preset time period wherein
More than or equal to preset times, then confirm that mistake occurs in the memory.
