Step 101, count value is upgraded, the count value after the renewal is used to identify LBA (Logical Block Addressing) information, and this LBA (Logical Block Addressing) information is corresponding with the data that current needs write;
Step 102, the data that current needs are write, LBA (Logical Block Addressing) information and upgrade after count value write the target physical piece.
When needs when the target physical piece writes data, at first, count value is upgraded count value after obtaining upgrading; Then, the count value after data, LBA (Logical Block Addressing) information and the renewal is write the target physical piece together.Through aforesaid operations, the page or leaf of the LBA (Logical Block Addressing) information correspondence of the count value after can guaranteeing to upgrade or the data of sector storage are effective, count value after wherein upgrading is used to identify LBA (Logical Block Addressing) information, this LBA (Logical Block Addressing) information is corresponding with the data that current needs write, and the page or leaf of this LBA (Logical Block Addressing) information correspondence or the data of sector storage are exactly the data that current needs write.
Present embodiment has been safeguarded LBA (Logical Block Addressing) information and count value, has upgraded after the count value count value after data, LBA (Logical Block Addressing) information and the renewal to be write the target physical piece.If mapping table is lost or be impaired, the page or leaf of the LBA (Logical Block Addressing) information correspondence of the count value can know renewal in the data reconstruction process after or sector data are effectively, and then realize the reconstruct of overall data, have strengthened the reliability of SSD.
In the embodiment of the invention, 1 shared space of physical block can comprise effective data field and redundant space, comprises that with 1 physical block 64 pages or leaves are example, and the valid data district of physical block can be divided into 64 parts, is respectively applied for the data of depositing each page; The redundant space of physical block also can be divided into 64 parts, is respectively applied for the redundant data of depositing each page, so 1 shared space of page or leaf comprises effective data field and redundant space.Comprise that with 1 page or leaf 8 sectors are example, the valid data district of page or leaf can be divided into 8 parts, is respectively applied for and deposits each sectors of data; The redundant space of page or leaf also can be divided into 8 parts, is respectively applied for the redundant data of depositing each sector.Certainly, page or leaf also can be safeguarded a redundant space, is used for the unified redundant data of all sectors of this page of depositing.
Fig. 2 is the process flow diagram of the embodiment of the invention two method for writing data in solid-state hard-disk.Present embodiment is that the unit management data describe as an example with page or leaf more than.When being the unit management data with page or leaf more than, the LBA (Logical Block Addressing) information that need write the target physical piece is specially the logical block number, and (LogicalBlock Number is called for short: LBN).If 1 page or leaf comprises 8 sectors, LBN is that LBA removes back three resulting address informations, and this is back three each sectors that is used for addressed page because of LBA, as being the unit management data with the page or leaf, as long as be addressed to page or leaf.
As shown in Figure 2, present embodiment specifically comprises the steps:
Step 201, the count value that external system is safeguarded are upgraded, and the count value after the renewal is used to identify LBN, and this LBN is corresponding for the data that write with current needs.
In SSD, can be that whole SSD safeguards a count value by external system, also can safeguard a count value for each passage by external system, wherein each passage comprises some FLASH.For example, be that whole SSD safeguards under the count value situation, when need the arbitrary target physical piece in this SSD writing data, upgrade the count value that this SSD safeguards.Safeguarding under the count value situation for each passage, when need the arbitrary target physical piece in a certain passage writing data, the count value that external system is safeguarded for passage under this target physical piece is being upgraded.
This step can be specially: the count value that external system is safeguarded adds the count value after obtaining after 1 upgrading.
Further, the renewal of count value operation is not limited only to add 1 operation, also can be operation clocklike arbitrarily, for example increment operation or decrement operations etc., and the step value of its increasing or decreasing also can be arbitrary preset value.
Describe below by two concrete examples:
1) renewal is operating as and adds 1 operation, and external system is the situation that whole SSD safeguards a count value:
The design value initial value is 0.When for the first time need a certain target physical piece writes data in SSD, count value be updated to 1 from 0; When for the second time need another target physical piece writes data in SSD, count value be updated to 2 from 1.
2) renewal is operating as and adds 1 operation, and external system is the situation that each passage is safeguarded a count value:
If SSD has two passages, be respectively passage A and channel B, the count value of passage A is first count value, and the count value of channel B is second count value, and the initial value of these two count values is 0.
When for the first time need a certain target physical piece writes data in passage A, first count value be updated to 1 from 0; When for the second time need a certain target physical piece writes data in channel B, second count value be updated to 1 from 0; When needing for the third time that another target physical piece writes data in passage A, first count value is updated to 2 from 1; When the 4th needs when another target physical piece writes data in channel B, second count value is updated to 2 from 1.
Above-mentioned two examples only are a kind of explanation to this process embodiment, but not to the restriction of this step.
This step with LBN and the count value after upgrading be stored together, also can read LBN when reading the count value after the renewal.
After step 202, present embodiment can also comprise: the PBA of page or leaf in the target physical piece is write in the mapping table as the up-to-date PBA of LBN.Just, after step 202, upgrade mapping table, the PBA of LBN correspondence is the PBA of page or leaf in the target physical piece in the mapping table after the renewal.
When present embodiment need write data, upgrade the count value that external system is safeguarded, data write the valid data district of page or leaf in the target physical piece, with LBN and the count value after upgrading write in the redundant space of page or leaf in the target physical piece.If mapping table is lost or be impaired, the page data of the LBN correspondence of the count value can know renewal in the data reconstruction process after is effectively, and then realizes the reconstruct of overall data, has strengthened the reliability of SSD.Further, present embodiment adopts the count value after redundant space storage LBN and the renewal thereof, does not need the outer storage space of occupying volume, and the utilization factor of disc is higher.Present embodiment with LBN and the count value after upgrading be stored together, count value after LBN and the renewal thereof is distributed in the overall FLASH particle of SSD like this, in the data reconstruction process, can concurrently read LBN and upgrade after count value, improved the speed of rebuilding.
