Specific embodiment
Accompanying drawing in below in conjunction with the embodiment of the present invention, to the embodiment of the present invention in technical scheme carry out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiment.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Fig. 1 is Nand Flash storage organization schematic diagrames；Solid state hard disc typically all supports concurrent operations, that is, supports many
Passage DIE simultaneously operating physical memory spaces, each passage DIE are made up of some data blocks Block, if each Block again by
Dry data page Page compositions；Different Flash techniques are different with the number of technical support, and the present embodiment is with a DIE by 1024
Individual Block composition, a Block are made up of 256 Page, and Block is the minimum erasing operation unit of Flash, and Page is
The minimum write unit of Flash, often re-write a Page data when, be required for the ECC check for recalculating the Page
Data, and write verification data area.
Fig. 2 is operating process schematic diagram when Nand Flash readings have abnormal, when NAND controller is sent to NAND
Read command, returns data to NAND controller after the loading of NAND internal datas, data include the ECC numbers of write when writing
According to NAND controller carries out data check according to the valid data and ECC data that read, judges whether the data for reading are correct.
For different technique is different with the ECC error correction bit numbers supported by the Nand Flash of technology, presently, there are support 1～
The ECC algorithm of 128bit/1KB, future are also possible to the ECC algorithm for supporting more bit, support that the ECC of several bit is exactly that permission is every
Occur the maximum bit numbers of bit reversal, that is, threshold values TH in the data of 1KB, as long as each 1KB data cell is all only in the Page
It is that the bit reversal less than the bit numbers occurs, correcting data error and recovery can be completed by ECC algorithm.When data occur different
When Chang Wufa passes through an error correction, also exist inside NAND FLASH by adjusting the electrical configurations parameter for reading, such as adjustment valve
The modes such as threshold voltage are re-reading during the Page data, and re-start verification, correct until reading by continuously attempting to
Data, or attempt all reading correct data until various, front end HPI is returned, the data exception is clearly identified.
Therefore, when data have exception, the whole operating lag for reading data is very big, has a strong impact on the response time of main frame.
Fig. 3 is data monitoring threading operation schematic flow sheet；The present invention is exactly to exist to reduce front end main frame as far as possible
It is the probability for running into data exception to access data, by increasing data monitoring thread and exception in solid-state hard disk controller
Refresh Data thread.As concurrent operations all supported by hard disk, data monitoring is individually increased according to the number of passage DIE preferably
Thread and abnormal data refresh thread, and each passage DIE is scanned respectively and refreshes；Data monitoring thread is in solid state hard disc control
When device processed is idle, that is, the valid data block that front end main frame is stored in automatically scanning solid state hard disc when not accessing, scan through
Whether correctly the digital independent of the paired valid data block simultaneously verifies the data block data, cannot entangle if there is wrong and data
Why mistake, be judged to data exception, then the data block information that there will be data exception is recorded；Block to be scanned is selected, by
The data of individual each Page of reading, start ECC error correction module, when data occur the threshold values TH of the bit numbers more than the FLASH of reversion
When, judge that the data are present abnormal, the Block is designated exception；When the bit numbers that data occur reversion are not more than the FLASH
Threshold values TH when, carry out correcting data error, return correct data.
Fig. 4 is the schematic diagram that abnormal data is flushed to new freed data blocks, and it is hard in solid-state that abnormal data refreshes thread
Data block Block of the presence data exception recorded according to data monitoring thread when disk controller is idle carries out data and reads again and entangle
Mistake, and by error correction after Refresh Data in other free memory blocks of solid state hard disc.The abnormal data one of same passage DIE
As all preferentially flush in other idle Block of passage DIE.
According to the physical characteristic of NAND FLASH, the programmable number of times of same Block has certain life-span to limit, quilt
Programming number of times is more, and the probability that data exception occurs in the Block is higher, can basis when therefore data monitoring thread is scanned
Block is programmed the size of number of times, and priority scan is programmed Block often, and Block is programmed number of times and can pass through to be somebody's turn to do
The erasing operation number of times of Block achieves that the monitoring of programming number of times embodying by recording the erasing operation number of times of Block.
Memory cell in same NAND FLASH be all by electric charge number come Division identification data, therefore data are deposited
The storage time is longer, then the probability of the electric charge presence leakage in the data is also higher, that is, there is the probability of data exception
Also higher, therefore can also increase record Block and be programmed that the time, can basis when therefore data monitoring thread is scanned
Block is programmed that time, priority scan are programmed secondary Block of long duration.
Above disclosed is only an embodiment of the present invention, can not limit certainly the interest field of sheet with this,
One of ordinary skill in the art will appreciate that realize all or part of flow process of above-described embodiment, and according to the claims in the present invention institute
The equivalent variations of work, still fall within the scope covered by the present invention.
