Description
Technical field
The present invention is with regard to a kind of data managing method of solid state hard disc, write management system and its method, special
Do not relate to it is a kind of can according to the write behavior of solid state hard disc, and further manage write data with
And update the write management system and its method of its firmware.
Background technology
Solid state hard disc (Solid-State Drive, abbreviation SSD) is a kind of with Nonvolatile memory internal memory work
For the computer storage device of permanent memory.The data access speed of Nonvolatile memory is between volatibility
Between internal memory and conventional hard.Compare with volatile ram, Nonvolatile memory once write data, just
Do not need extraneous electric power to maintain which to remember.Therefore it is more suitable as the succedaneum of conventional hard.And flash memory
Central NAND Flash are then modal Nonvolatile memories.Manufacturer need to only use flash memory, then match somebody with somebody
The control chip properly worked as, just can produce solid state hard disc.
One NAND Flash memory chip is made up of several blocks (block), and each block is
It is made up of several pages (page), a page contains user area (User area) and area of space
(Space), the former is responsible for storage write data, the latter's storage Mapping information (Mapping information)
And error correcting code (Error Correcting Code).It is noted that the write of flash memory is substantially single
Position is a page, and its action of erasing is then a block for unit, and each block institute energy in flash memory
The number of times erased has its higher limit.
And as solid state hard disc is different from conventional hard in physical characteristics, therefore solid state hard disc make use of one layer
FTL (Flash Translation Layer) is emulated into conventional hard, due to NAND Flash internal memories
In-Place update cannot be carried out in same address, thus FTL can by the data for repeating to update write to
Other addresses are deposited, and using mapping table (Mapping table) recording the address after renewal.
When all blocks are all written can be write without exceptional space, FTL can call Garbage
Collection (GC) actions reclaim space so that other data write removing invalid paging.In addition
FTL can also provide average abrasion process, extend the use life cycle of flash memory, and the mistake for carrying out data
Correct by mistake, verify the correctness of write data.
In general, FTL can be divided into high parsing mapping (High-resolution mapping), harmonic analysis pair
(Low-resolution mapping) and mixing mapping (Hybrid mapping) are reflected, one is using less
Correspond to unit to carry out address conversion, such as Page-Level mapping, with excellent random writing speed,
But need a page table to record the corresponding address of each page.It is then single using larger correspondence both the
Position carrying out address conversion, such as Block-Level mapping, as which is in units of block, therefore required
Form is minimum, if but write data be discontented with a block when, need additionally to fill this block, in other words
Say, if carry out low volume data write, the mode of harmonic analysis mapping needs many extra replication actions,
Therefore its performance extreme difference on random access memory.The third party is to be mixed with high parsing mapping and harmonic analysis mapping
Mode, it is Log block that the data of new write are write by which in Page-Level mapping modes, and
Only Log block need page table to record the corresponding address of every one page, and its hardware cost for expending then is situated between
Between Page-Level mapping and Block-Level mapping, and mix mapping the disadvantage is that,
After Log block are depleted, FTL can start GC to reclaim space, and mix mapping must be by
The valid data of valid data and same logical blocks belonging to which in Log Block, are all copied to new
Block and be organized into data block pattern storage, its will may require that it is a series of duplication and action of erasing
And causing extra burden so that solid state hard disc efficiency declines.
User understands the use state of solid state hard disc for convenience, and solid state hard disc can built-in S.M.A.R.T
To provide the usage degree about solid state hard disc, so that user estimates the service life of solid state hard disc.But by
It is different from write mode in the use condition of each main frame, for expected life can produce very big error.
And the difference of write mode is often for the firmware framework of solid state hard disc can produce the error of very different,
It is possible to cause unnecessary data to move and write.For example, when the FTL of this solid state hard disc is low
Parsing mapping when, if its write each pen data usually be discontented with a block, can not only produce compared with
Poor access efficiency, can also shorten the life-span of this solid state hard disc.On the contrary, as the FTL of this solid state hard disc
When parsing mapping for height, if data of its write belong to multiple continuous blocks, its random writing speed
Advantage then do not see again.
