Embodiment
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
First technical background of the present invention is introduced.
In the embodiment of the present invention, solid state hard disc can be the hard disk made with solid-state electronic storage chip array.At present, the storage medium of solid state hard disc generally can by two kinds, one adopts flash memory (FLASH) chip as storage medium, and another adopts dynamic RAM (DynamicRandomAccessMemory, DRAM) as storage medium.Wherein, adopt FLASH chip as the solid state hard disc of storage medium, namely usually said SSD, its outward appearance can be made into multiple apperance, such as: the patterns such as laptop hard, micro harddisk, storage card, USB flash disk.
Such as refer to Fig. 1, solid state hard disc can comprise controller 101 and storer 102.
Controller 101 can be such as the control chip in solid state hard disc, control chip is the brain of solid state hard disc, its effect one is the load on rational allocation data each flash chip in solid state hard disc, second be assume responsibility for whole data relay, connect flash chip and outside SATA (SerialAdvancedTechnologyAttachment, serial hard disk interface technology) interface.
Storer 102 can be such as the storage medium in solid state hard disc, is such as flash chip or DRAM, may be used for storing data.
In addition, can also comprise cache chip in some solid state hard discs, cache chip at a high speed can carry out data processing by auxiliary control chip.What relate generally to due to the embodiment of the present invention is controller 101 and storer 102, so do not draw cache chip in the drawings.
At present, when the data stored in solid state hard disc need to refresh, solid state hard disc can be connected to main frame (such as personal computer), by main frame, the data stored in solid state hard disc be refreshed.But this mode needs main frame and solid state hard disc to carry out could realizing alternately the refreshing of data, limitation is comparatively large, and the self-repairing capability of solid state hard disc is more weak.
The embodiment of the present invention fully takes into account above problem, can determine whether solid state hard disc meets predetermined condition by the controller 101 of solid state hard disc, thus determine whether to exist in solid state hard disc the data needing to refresh, under having data to need brush news in solid state hard disc, can directly by controller 101 analyze solid state hard disc historical data thus determine need refresh be which data stored in solid state hard disc.By such mode, without the need to carrying out alternately with main frame, solid state hard disc just directly can determine that the data stored in solid state hard disc are the need of refreshing, and determine need refresh be which data, weaken the dependence to external unit, enhance the self-repairing capability of solid state hard disc.
Below in conjunction with accompanying drawing, the preferred embodiment of the present invention is described in detail.
Refer to Fig. 2, the embodiment of the present invention provides a kind of method for refreshing data, and the method can be performed by solid state hard disc, and such as can be performed by the controller 101 of solid state hard disc, the flow process of the method is described below.
Step 201: when the controller 101 by solid state hard disc determines that solid state hard disc meets predetermined condition, obtained the historical data of solid state hard disc by the controller 101 of solid state hard disc; Historical data is used to indicate the behaviour in service of solid state hard disc;
Step 202: by controller 101 analysis of history data, to determine the data needing in solid state hard disc to refresh.
Historical data may be used for the behaviour in service indicating solid state hard disc.Such as, historical data can comprise data corresponding to data corresponding to the power on moment that be each time energized of solid state hard disc from first time energising starts, power-cut time and energising continues data corresponding to duration, or, historical data also can comprise the time data that each data that storer 102 in solid state hard disc stores are read or write, or, historical data can also comprise in the storer 102 of solid state hard disc the last time data be refreshed of each data stored, etc.As long as the data being used to refer to the behaviour in service of solid state hard disc can comprise in the historical data.
Predetermined condition, is namely used for determining that data that the storer 102 in solid state hard disc stores are the need of the condition refreshed, when solid state hard disc meets predetermined condition, then can determines to store in the storer 102 of solid state hard disc the data needing to refresh.About determining whether solid state hard disc meets the mode of predetermined condition, introduction of below illustrating.
The first:
Optionally, in an alternative embodiment of the invention, determine that solid state hard disc meets predetermined condition by the controller 101 of solid state hard disc, comprising:
Determine that solid state hard disc is in off-position in the first preset duration by controller 101; The terminal moment of the first preset duration is current time;
Determine that solid state hard disc meets predetermined condition by controller 101.
First preset duration can be the terminal moment is any duration of current time.Such as, when current time is such as 17 days 10 September in 2015, the first preset duration can be such as from current time forward 30 days, so the first preset duration can be just from during 18 days 10 August in 2015 to this section of duration during 17 days 10 September in 2015.
Generally, if solid state hard disc is all in off-position for a long time, can think that solid state hard disc does not all use for a long time, therefore, likely exist because the electric charge be stored in solid state hard disc reduces and cause the situation that the data stored make a mistake.In this case, can think to there are the data needing to refresh in storer 102.
In the embodiment of the present invention, predetermined condition can be that solid state hard disc is in off-position in the first preset duration, such as, controller 101 can detect data corresponding to the last power-cut time be energized of solid state hard disc, if the power-cut time of last energising is not within the time period that the first preset duration is corresponding, then can determine that solid state hard disc is in off-position in the first preset duration, so can determine that solid state hard disc meets predetermined condition, namely determine in solid state hard disc, to there are the data needing to refresh.
Such as, when current time is such as 1 day 12 October in 2015 30 points, first preset duration is such as from current time forward 60 days, that is, this section of duration when the first preset duration can be 2 days 12 August in 2015 during 30 points to 2015 on October 1,12 between 30 points.If controller 101 gets the power-cut time of solid state hard disc last time energising when 2 days 12 August in 2015 before 30 points, when being such as 1 day 16 April in 2015 30 points, or when being just in time 2 days 12 August in 2015 30 points, then can determine that solid state hard disc is in off-position in the first preset duration, also just determine that solid state hard disc meets predetermined condition.
Like this, solid state hard disc is without the need to by mutual with main frame, just can determine that the data stored are the need of refreshing by the controller 101 of self, process comparatively easily realizes, and detect solid state hard disc whether have energising in certain time length, can determine that data in storer 102 are the need of refreshing comparatively convenient and exactly.
Optionally, in an alternative embodiment of the invention, by controller 101 analysis of history data, to determine the data needing in solid state hard disc to refresh, comprising:
By controller 101 analysis of history data, determine that the total data in solid state hard disc is the data needing to refresh.
In the embodiment of the present invention, if determine that solid state hard disc is in off-position in the first preset duration by controller 101, then can analyze the historical data of solid state hard disc, at this moment historical data can be the data corresponding to power-cut time of solid state hard disc last time energising, or the data that the size of the data total amount stored in storer 102 is corresponding.
Usually, if solid state hard disc is not energized for a long time, then can show that all data stored in storer 102 are all not updated in a long time, the analysis of data that so can be corresponding by the power-cut time be energized to the last time, is all defined as the data needing to refresh by the total data stored in storer 102.
Or, for new solid state hard disc, storer 102 just may store a small amount of data when dispatching from the factory, and such as, stores some for recovering the software of data, therefore, if according to the analysis to historical data, show that the data total amount stored in storer 102 is very little, just likely think that solid state hard disc is new, thus can according to the analysis of size to the data total amount stored in storer 102, think that the data stored in storer 102 do not need to refresh.
Such as, coexist in storer 102 and contain data 1, data 2 and these 3 data of data 3, when current time is such as 1 day 12 October in 2015 30 points, first preset duration is such as from current time forward 60 days, controller 101 has determined that solid state hard disc is in off-position in the first preset duration, so can analyze historical data, such as historical data can be the power-cut time of solid state hard disc last time energising, such as, when being 3 days 12 May in 2015 30 points, thus, the total data that controller 101 can will store in storer 102, namely data 1, data 2 and data 3 are all defined as the data needing to refresh.Like this, total data is all defined as the data needing to refresh, comparatively comprehensively can guarantees the reliability of the data stored in storer 102.
Or such as, data 1 are only stored in storer 102, when current time is such as 1 day 12 October in 2015 30 points, first preset duration is such as that controller 101 has determined that solid state hard disc is in off-position in the first preset duration, so can analyze historical data from current time forward 60 days, such as historical data can be the size of data 1, if the size of data 1 is less than certain preset value, be such as less than 1KB, then can think that data 1 do not need to refresh.By such mode, the refresh activity to new solid state hard disc effectively can be avoided.
The second:
Optionally, in an alternative embodiment of the invention, determine that solid state hard disc meets predetermined condition by the controller 101 of solid state hard disc, comprising:
Determine to be included in not by the data read in the second preset duration in the data that solid state hard disc stores by controller 101, or determined in the data that solid state hard disc stores not included in the data write in the second preset duration by controller 101; The terminal moment of the second preset duration is current time;
Determine that solid state hard disc meets predetermined condition by controller 101.
Second preset duration equally also can be the terminal moment is any duration of current time.Such as, current time is such as 10 o'clock sharps of on September 17th, 2015, second preset duration can be such as that so the second preset duration can be just from this section of duration 10 o'clock sharps of 10 o'clock sharps of on August 18th, 2015 on September 17th, 2015 from current time forward 30 days.
User uses in the process of solid state hard disc in reality, likely often access be a part of data in the data that store of storer 102, seldom even almost may not access another part data that storer 102 stores.Such as, store some data such as photo in the memory 102 or video, user may can not often browse, so situation about making a mistake just likely be there will be for seldom those a part of data accessed, so be necessary regularly to refresh seldom accessed data, therefore, can think in this case in solid state hard disc, to there are the data needing to refresh.
In this embodiment, controller 101 can obtain each data stored in the solid state hard disc the last time be read, thus determine whether each data were read in the second preset duration, if in the second preset duration, the data be not read are had in the data stored in storer 102, so can determine that solid state hard disc meets predetermined condition, namely determine in solid state hard disc, to there are the data needing to refresh.
Or, in this embodiment, controller 101 can according to the time of each data write solid state hard disc stored in storer 102, determine in the second preset duration, whether have data to write, if do not write data in solid state hard disc in the second preset duration, so can determine that solid state hard disc meets predetermined condition, namely determine in solid state hard disc, to there are the data needing to refresh.
Such as, the data that storer 102 stores comprise data 1, when current time is such as 1 day 12 October in 2015 30 points, second preset duration is such as from current time forward 60 days, that is, this section of duration when the second preset duration can be 2 days 12 August in 2015 during 30 points to 2015 on October 1,12 between 30 points.If when knowing that the time that data 1 the last time is read is 3 days 11 July in 2015 by controller 101 50 points, so can think that solid state hard disc meets predetermined condition, namely determine in solid state hard disc, to there are the data needing to refresh.
Or such as, when current time is such as 1 day 12 October in 2015 30 points, second preset duration is such as from current time forward 60 days, that is, this section of duration when the second preset duration can be 2 days 12 August in 2015 during 30 points to 2015 on October 1,12 between 30 points.If detect all do not have data to write in the second preset duration by controller 101, so can think to there are the data needing to refresh in solid state hard disc, namely determine that solid state hard disc meets predetermined condition.
More adequately can determine whether to exist in solid state hard disc the data needing to refresh by the way.
Optionally, in an alternative embodiment of the invention, if determine to be included in the data that solid state hard disc stores in the second preset duration not by the data read by controller 101, then, by controller 101 analysis of history data, to determine the data needing in solid state hard disc to refresh, comprising:
By controller 101 analysis of history data, to determine in the second preset duration being not the data needing to refresh by the data read.
In the embodiment of the present invention, being determined to exist in the second preset duration not by after the data read by controller 101, controller 101 can to historical data analysis, here historical data can be the time data be read each data the last time stored in storer 102, thus can to determine in the second preset duration which being not by the data read, and these are not defined as the data that need to refresh by the data read.
Such as, the data that storer 102 stores comprise data 1 and data 2, when current time is such as 1 day 12 October in 2015 30 points, second preset duration is such as from current time forward 60 days, that is, 30 points of this section of durations during 30 points to 2015 on October 1,12 when the second preset duration can be 2 days 12 August in 2015.Can be analyzed by controller 101 pairs of historical datas, such as historical data can be that data 1 the last time is by the time of reading, when being such as 28 days 11 September in 2015 10 points, and data 2 the last time is by the time of reading, be such as 17: 50 on the 30th June in 2015, so by controller 101, data 2 can be defined as the data needing refreshing.
Can do not thought by the data read the data that user seldom accesses for a long time, this part data may easily be made mistakes or lose, so by long-time be not the data needing to refresh by the data validation read, the reliability of solid state hard disc can be improved, and in the process of Refresh Data, can refresh partial data targetedly, save the time of Refresh Data, alleviated the work load that Refresh Data brings.
Optionally, in an alternative embodiment of the invention, if determined in the data that solid state hard disc stores not included in the data write in the second preset duration by controller 101, then, by controller 101 analysis of history data, to determine the data needing in solid state hard disc to refresh, comprising:
By controller 101 analysis of history data, determine that the total data in solid state hard disc is the data needing to refresh.
In the embodiment of the present invention, if determine do not have data to be written in the second preset duration by controller 101, then controller 101 can be analyzed historical data, here historical data can be the time data that each data of storer 102 storage are written into, thus the total data stored in solid state hard disc can be defined as the data needing refreshing.
Or, historical data also can be the time data be read each data the last time stored in storer 102, if do not have data to be written into solid state hard disc in the second preset duration, but having in storer 102 by the data read, so can be defined as by the total data beyond the data read the data that need to refresh by removing in solid state hard disc in the second preset duration.
Such as, storer 102 comprises data 1 and data 2, when current time is such as 1 day 12 October in 2015 30 points, second preset duration is such as from current time forward 60 days, that is, 30 points of this section of durations during 30 points to 2015 on October 1,12 when the second preset duration can be 2 days 12 August in 2015.If the write time of data 1 and data 2 is all early than during 2 days 12 August in 2015 30 points, so can analyze historical data, such as historical data can be the write time of data 1 is 11: 30 on the 12nd June in 2015, and the write time of data 2 is 12: 30 on the 11st June in 2015, just can determine the total data in solid state hard disc, namely data 1 and data 2 are the data needing to refresh.
Usually, within a period of time, all do not have data to write, so can think that the data stored in solid state hard disc all need to refresh.Like this, total data is all defined as the data needing to refresh, comparatively comprehensively can guarantees the reliability of the data stored in solid state hard disc.
Or such as, storer 102 comprises data 1, data 2 and data 3, when current time is such as 1 day 12 October in 2015 30 points, second preset duration is such as from current time forward 60 days, that is, 30 points of this section of durations during 30 points to 2015 on October 1,12 when the second preset duration can be 2 days 12 August in 2015.If the time that data 1, data 2 and data 3 write solid state hard disc is all early than during 2 days 12 August in 2015 30 points, so can analyze historical data, here historical data can be such as the time data be read three data the last times, if historical data shows in the second preset duration, data 3 are only had to be read, so can by storer 102, the total data beyond removing data 3, namely data 1 and data 2 are defined as the data needing refreshing.
Due in actual use, likely there is read-only fetching data and do not write the situation of data in solid state hard disc, therefore when not having data to write for a long time, again the time data that the last time of the data stored is read is analyzed, thus determine to need the mode of the data refreshed can filter out the data needing refreshing more accurately.
Optionally, in an alternative embodiment of the invention, after determining the data needing in solid state hard disc to refresh, also comprise:
Refreshed needing the data refreshed by the controller 101 of solid state hard disc.
In the embodiment of the present invention, determine in solid state hard disc the data that have and need to refresh and need to refresh be which partial data after, can by controller 101 directly to needing the data refreshed refresh.
Such as, the data stored in storer 102 comprise data 1, data 2 and data 3, determine to need the data refreshed to be data 2 and data 3, so directly can be refreshed data 2 and data 3 by controller 101.By such mode, solid state hard disc need not be connected with main frame, namely solid state hard disc is without the need to carrying out alternately with main frame, and just can realize the refreshing of data, solid state hard disc self-repairing capability is stronger.
In the embodiment of the present invention, can determine whether solid state hard disc meets predetermined condition thus determine whether to exist in solid state hard disc the data of needs refreshing by the controller 101 of solid state hard disc, under having data to need brush news in solid state hard disc, can by controller 101 analyze solid state hard disc historical data thus determine need refresh be which data stored in solid state hard disc.By such mode, without the need to carrying out alternately with main frame, solid state hard disc just directly can determine that the data stored in solid state hard disc are the need of refreshing, and determine need refresh be which data, weaken the dependence to external unit, enhance the self-repairing capability of solid state hard disc.
