Fig. 1 is refer to, the flow process of the process of the method for data-moving in a kind of solid state hard disc that Fig. 1 is provided for the present invention
Figure, the method include：
Step S101：Determine physical block to be recycled；
Preferably, the process for determining physical block to be recycled is：
Physical block to be recycled is determined according to dynamic and static equilibrium algorithm.
Specifically, when garbage reclamation is carried out, it is necessary first to determine physical block to be recycled, here can according to dynamic and
Static equilibrium algorithm is determining physical block to be recycled, naturally it is also possible to determined using other algorithms, and the present invention is for concrete
Which kind of algorithm to determine physical block to be recycled is not particularly limited using, determined according to practical situation.
Step S102：Determine all active pages in physical block；
Step S103：When the original bit bit error rate of active page is less than predetermined threshold value, move according to NAND internal datas
Instruct the blank page in the data-moving in active page to physical block.
It is understood that how many expressions 1 or 0 in NAND according to electronics, if NAND is caused by external interference
Electronics increases or reduces, and bit reversions will occur, and such as 1 is changed into 0 or 0 is changed into 1, will send out when digital independent is carried out
Raw mistake, is at this moment accomplished by NADA controllers and possesses error correction algorithm, ensure the bit of more rotating.But in fact, error correction algorithm
Error correcting capability have certain capacity, for example, the error correcting capability of error correction algorithm is 120bit, in theory when the active page of NAND
In Data flipping bit numbers be less than 120bit when, error correction algorithm can be corrected, that is to say, that having in NAND
When the RBER (Raw Bit Error Rate, the original bit bit error rate) of effect page data is not very big (such as during 10bit), need not
In order to the very first time corrects the error in data in active page, every time data are first moved on DDR when data-moving is carried out,
Effectively page data occur to be corrected using NAND error correction algorithms when bit overturns after again by the active page data-moving on DDR extremely
In the blank page of NAND, this mode significantly increases process time during garbage reclamation so that the readwrite bandwidth of user is reduced
Increase with time delay.
In the application, it is determined that after all active pages of physical block, judge the RBER of each active page one by one, work as active page
RBER be less than predetermined threshold value when, according to NAND internal datas move instruction directly by the data-moving in active page to physical block
In blank page, and without the need for by the data-moving in active page to DDR, again the data in active page being removed after physical block erasing
The new blank page obtained after moving to erasing.
Preferably, when the original bit bit error rate of active page is less than predetermined threshold value, remove according to NAND internal datas
Moving instruction by the process of the blank page in the data-moving in active page to physical block is：
The affecting parameters of the original bit bit error rate of active page are obtained from mapping table, wherein, affecting parameters include effectively
Move the erasable number of times and/or Current Temperatures of number of times and/or physical block in the inside of page；
When affecting parameters meet it is pre-conditioned when, move instruction by the data-moving in active page according to NAND internal datas
Blank page into physical block, wherein, it is pre-conditioned correspondingly including active page inside move number of times less than first threshold and/
Or the erasable number of times of physical block is less than Second Threshold and/or Current Temperatures are less than the 3rd threshold value.
It is understood that RBER is relevant with the use time of NAND, the use time of NAND it is longer (physical block it is erasable
Number of times embodies), RBER is accumulative to become big.Specifically, the erasable number of times of physical block is more, and the number of times of instruction can be moved with internal data
Fewer, in addition, RBER is also relevant with temperature (temperature affects the active degree of electronics), temperature is higher, and RBER is easier to become big.It is logical
In the case of often, carry out at normal temperatures moving best.
Specifically, because without error correcting when moving instruction moving data using NAND internal datas, so with
The increased frequency moved, in active page, the bit of mistake also can be more and more, namely incorrect integration occurs, therefore, this is accomplished by
Number of times is moved in the inside for recording each active page, when number of times is moved more than first threshold in inside, then needs to be switched to outside and refers to
Data-moving is done in order, does a Data correction.
Therefore, in the application, " affecting parameters meet pre-conditioned " represents that now " the original bit bit error rate of active page is little
In predetermined threshold value ".
Specifically, when affecting parameters include that number of times, the erasable number of times of physical block and Current Temperatures are moved in the inside of active page
When, then " affecting parameters meet pre-conditioned " namely the inside of active page now move number of times less than first threshold, physical block
Erasable number of times be less than Second Threshold and Current Temperatures and be less than the 3rd threshold value.When the inside that affecting parameters comprise only effect page is moved
During the erasable number of times of number of times and physical block, then " affecting parameters meet pre-conditioned " namely the inside of active page now are moved time
Number is less than Second Threshold less than the erasable number of times of first threshold and physical block, and other situations are also in the same manner.
Preferably, first threshold is 100 times, and Second Threshold is 10 times, and the 3rd threshold value is 50 DEG C.
Certainly, first threshold here, Second Threshold and the 3rd threshold value can also be specially other numerical value, here of the present invention
It is not particularly limited, is determined according to practical situation.
Preferably, the method also includes：
When the original bit bit error rate of active page is not less than predetermined threshold value, switch external command by the data in active page
Move to DDR, and when being corrected using NAND error correction algorithms when bit overturns occur in the data in active page, treat that physical block is wiped
The new the blank page again data-moving in the active page after correction obtained to after wiping after removing.
Preferably, the method also includes：
Number of times clearing is moved in the inside of active page.
Specifically, after external algorithm correction is finished, subsequent dynamic is realized by inside is moved number of times clearing and predicted
The size of RBER.
The invention provides in a kind of solid state hard disc data-moving method, including determine physical block to be recycled；It is determined that
All active pages in physical block；When the original bit bit error rate of active page is less than predetermined threshold value, according to NAND internal datas
Instruction is moved by the blank page in the data-moving in active page to physical block.It can be seen that, the present invention is meeting the original of active page
When bit error rate is less, move instruction the data in active page directly to be moved into physical block using NAND internal datas
Blank page, an internal data transfer substantially reduces the recycling time of rubbish, and need not outwards transmit number
According to this and outside carries out data and re-writes, the readwrite bandwidth of user is not take up, the read-write time delay of user is substantially reduced.
