Embodiment belongs to the scope of the present invention.
In order to enable those skilled in the art to better understand the solution of the present invention, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.
Next, a kind of data block processing method provided by the embodiment of the present invention is discussed in detail.
Fig. 1 is a kind of flow chart of data block processing method provided in an embodiment of the present invention, this method comprises:
S101: judge whether each data block has data write-in within a preset time.
It include multiple data blocks in a storage equipment such as 3D NAND, the time that data store in data block gets over
Long, bigger to the stability influence of legacy data in the data block when new data writing data blocks, therefore, in the embodiment of the present invention
In, in order to promote the stability of data in data block, preset time can be set, to write times of data in each data block into
Row detection.
It, then can will be in preset time when there is the data block that data are not written within a preset time in all data blocks
The data block of data is not written as target data block, executes the operation of S102.
The processing mode of each data block is similar, in the concrete realization, can be from the data block by taking a data block as an example
It completes to start timing when the write-in of data for the first time, if reach preset time, which never has the write-in of new data, then
The operation of S102 can be executed.After the data block completes the write-in of data for the first time, there is the write-in of new data within a preset time,
Then it can restart timing using the time that new data completes write-in as initial time, detect the number when reaching preset time
Whether there is the write-in of new data according to block, and so on, until the data block stops write-in data.
Wherein, the value of preset time can require to be set according to the BER of data block.In embodiments of the present invention,
According to experimental verification, the preset time of data block can be set to 2 hours.I.e. whether detection data block has newly in 2 hours
The write-in of data can then execute the operation of S102 when the data block interior never write-in of new data when 2 is small.
S102: filling in invalid data in target data block, and stops the label of write-in data for target data block setting.
Target data block is the data block of no data write-in within a preset time.Since the target data block long period does not have
There is the write-in of new data, then can fill in invalid data in the target data block, and stop write-in for target data block setting
New data are no longer written in the target data block at this time in the label of data, so as to reduce new data write-in to number of targets
It is influenced according to block bring.
By taking a data block as an example, the data of the data block are ultimately written often than the error bit of previously written data
Rate is high, in embodiments of the present invention, can be to the reality stored in data block by filling in invalid data in target data block
Data are protected, to reduce the wrong bitrate of data block.
Wherein, the data volume size for the invalid data filled in can require to be set according to the BER of data block.In this hair
In bright embodiment, according to experimental verification, the data volume of invalid data can be dimensioned to 48KB.Data block is by data page group
At three adjacent data pages constitute a data line (Word Line, WL).Wherein, a data page can store 4KB number
According to corresponding 4 data lines i.e. 12 data pages of corresponding 48KB.In the concrete realization, 12 data page storage nothings can be set
Data are imitated, i.e. the predetermined number for storing invalid data is 12.
In view of in practical applications, the idle data page in data block may be less than the predetermined number of setting, therefore
Before filling in invalid data, it can first judge whether the number of the idle data page in target data block is greater than or equal to default
Number.
When the number of the idle data page in target data block is greater than or equal to predetermined number, then illustrate the target data
Block has enough memory spaces for storing invalid data, in order to realize the effective protection to real data in target data block,
Invalid data is filled in the idle data page of predetermined number that can be adjacent with real data in target data block.
It is assumed that including 521 data pages, respectively data page 0- data page 520, data page 0- number in a data block
According to real data is stored in page 257, data page 258- data page 520 is idle data page at this time.When default of setting
When number is 12, then invalid data can be filled in data page 258- data page 269.
When the number of the idle data page in target data block is less than predetermined number, then illustrate that the target data block does not have
Enough memory spaces then can fill in invalid data in all idle data pages at this time for storing invalid data.
It is assumed that including 521 data pages, respectively data page 0- data page 520, data page 0- number in a data block
According to real data is stored in page 515, data page 516- data page 520 is idle data page at this time.When default of setting
When number is 12, idle data page is not achieved 12, at this time then directly to remaining all idle data pages, that is, data page 516- number
Invalid data is filled according to page 520.
In embodiments of the present invention, without limitation for the concrete form of invalid data.Invalid data not supplemental characteristic
Practical reading therefore even if mistake occurs in invalid data, the BER of data block can't also be impacted.But it inserted
More invalid datas needs to spend the more time, therefore, in embodiments of the present invention, by setting predetermined number to filling in
The data volume of invalid data is defined, to realize the equilibrium between time-consuming and BER.
Judge whether each data block has data write-in within a preset time it can be seen from above-mentioned technical proposal；When depositing
In the target data block of the write-in of no data within a preset time, then illustrate that the target data block long period does not have new data
It is written, the time of data storage is more long in data block, to the stability influence of legacy data in the data block when new data is written
It is bigger, lead to the reliability decrease of data in the data block.And the data being ultimately written are often than previously written data
Wrong bitrate is high, therefore, in the technical scheme, then can be when target data block is written in no data in preset time
Invalid data is filled in the target data block, and stops the label of write-in data for target data block setting, at this time the mesh
New data are no longer written in mark data block, target data block bring is influenced so as to reduce new data write-in.And
Invalid data is filled in target data block, improves the reliability of real data in target data block.Especially reading intensively
Under application scenarios, effectively reduce BER when being read out to data block, with this guarantee the reading BER of data block maintain compared with
Low level ensure that whole disk error rate and QOS, effectively increase SSD product competitiveness.
The value of predetermined number can be arranged according to experimental verification by referring in the introduction above, in embodiments of the present invention,
In order to enable the value of predetermined number is more bonded actual demand, the Regulation mechanism of predetermined number can be set.
Specifically, filling in invalid data in target data block, and stop the mark of write-in data for target data block setting
After note, the wrong bitrate of target data block can also be detected；Value according to wrong bitrate adjustment predetermined number.
When reading data from target data block, target data can be calculated according to the correctness for reading data
The wrong bitrate of block.
In the concrete realization, the wrong bitrate of target data block can be repeatedly counted, it is true by way of being averaged
A wrong bitrate for making target data block, so that calculated wrong bitrate is more in line with actual conditions.
When wrong bitrate is higher, then predetermined number can be tuned up, be filled in vain according to the predetermined number after tuning up
Data, and when reading data, the wrong bitrate of data block is recalculated, when the wrong bitrate adjusts it than predetermined number
When preceding wrong bitrate declines, then the value of predetermined number can be further tuned up, and so on, until the wrong bitrate
When approaching constant with the wrong bitrate before the adjustment of last predetermined number, then it can stop the value for adjusting predetermined number.
Opposite, when the wrong bitrate increases than the wrong bitrate before predetermined number adjustment, then can further turn down pre-
If the value of number, until when the wrong bitrate approach before the wrong bitrate and last predetermined number adjustment is constant,
It can then stop adjusting the value of predetermined number.
The value of preset time is also to influence the factor of data block BER, similar with the adjustment value of predetermined number, in this hair
In bright embodiment, the value of preset time can also be adjusted according to wrong bitrate.
When wrong bitrate is higher, then preset time can be turned down, detect each number according to the preset time after turning down
Whether there is data write-in according to block, and when reading data, recalculate the wrong bitrate of data block, when the wrong bitrate ratio
When wrong bitrate before preset time adjustment declines, then the value of preset time can be further turned down, and so on, directly
When wrong bitrate approach before to the wrong bitrate and last preset time adjustment is constant, then it is pre- can to stop adjustment
If the value of time.It is opposite, it, then can be with when the wrong bitrate increases than the wrong bitrate before preset time adjustment
The value of preset time is further tuned up, until the wrong bitrate before the wrong bitrate and last preset time adjustment
When approaching constant, then it can stop the value for adjusting preset time.
In embodiments of the present invention, by being adjusted to preset time and predetermined number, can make preset time and
The value of predetermined number is more bonded the actual conditions of data block, to further decrease the wrong bitrate of data block.
