Wherein, due to Physical Page that described sub-storage unit can be in described storage unit; Accordingly, described first address information and the second address information may be used for characterizing positional information corresponding to described Physical Page.Such as, the first address information is the Physical Page 1 of chip one, just shows that storage first data are in Physical Page 1; Suppose that the second address information is the Physical Page 1 of chip three, just show that the Backup Data of storage first data is in the Physical Page 1 of chip three.
Include at least one group of data in described storage area mapping table and store corresponding relation.
Second storage area described in the present embodiment can be user's invisible area, such as, a storage unit can provide the storage space of 64G altogether, owing to wherein dividing out 12G to the second storage area, and the second storage area is recessive existence, so being shown to the visible storage space of user may be 54G.
Based on the storage area mapping table that such scheme generates, the embodiment of the present invention additionally provides and reads data based on storage area mapping table, and described Data Management Unit, also for receiving data read command; Based on described data read command, extract the first data from described first storage area; Judge whether described first data meet second pre-conditioned, wherein, the proof test value that described second pre-conditioned characterization data is corresponding meets first threshold; If described first data do not meet second pre-conditioned, then the data got from described storage area mapping table for described first data store corresponding relation; Store corresponding relation based on the data for described first data, get the Backup Data of the first data from described second storage area.
Wherein, based on described data read command, extracting the first data from described first storage area, can be the mark according to the first data in data read command, find at least one sub-storage unit of described storage first data, extract from the sub-storage unit of correspondence and obtain the first data.
Described Data Management Unit, specifically for verifying the first data extracted, obtains proof test value.Wherein, the method for described verification can have the methods of calibration such as parity checking, cyclic redundancy data check (CRC, CyclicRedundancyCheck), MD5.Accordingly, described first threshold can according to the corresponding different threshold value of different methods of calibration, if the proof test value of the first data obtained is in the scope of first threshold, then determine that described first data meet second pre-conditioned, namely described first data are partial data; If the proof test value of the first data is not within the scope of first threshold, then the first data are deficiency of data, now, just need the Backup Data of acquisition first data.
Described Data Management Unit, also for the Backup Data based on described first data, revises described first data, obtains revised described first data; Revised described first data are saved to described first storage area.
Wherein, to the method that described first data are revised can be: utilize the comparison that the Backup Data of the first data and described first data are carried out by turn, determine data bit different from the Backup Data of described first data in the first data, the data bit in the Backup Data of described first data is filled to data bit corresponding to described first data.
Or, to the method that described first data are revised can also be: directly using the Backup Data of described first data as described first data.
Preferably, above-mentioned being saved to can for being still kept at described revised first data in the sub-storage unit of former first data preservation in described first storage area.
Visible, by adopting such scheme, just storage unit at least can be divided out two storage areas, in these two storage areas, store respectively and meet first pre-conditioned the first data and Backup Data thereof, and the storage relation of preserving the first data and Backup Data thereof is in storage area mapping table.So, storage unit just can be avoided to the loss of data generation stored or the problem of damage, to ensure that in storage unit the reliability storing data due to storage life or other reasons.
