Specific implementation mode
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.Obviously, described embodiments are only a part of the embodiments of the present invention, rather than
Whole embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Lower obtained every other embodiment, shall fall within the protection scope of the present invention.
Term " first ", " second ", " third " " in the description and claims of this application and above-mentioned attached drawing
Four " etc. be for distinguishing different objects, rather than for describing specific sequence.In addition term " comprising " and " having " and
Their any deformations, it is intended that cover and non-exclusive include.Such as contain the process of series of steps or unit, method,
The step of system, product or equipment are not limited to list or unit, but the step of may include not listing or unit.
After describing the technical solution of the embodiment of the present invention, the various non-limiting realities of detailed description below the application
Apply mode.
Referring first to Fig. 1, Fig. 1 is that a kind of flow of the data read-write method of solid state disk provided in an embodiment of the present invention is shown
It is intended to, is based on multi-plane, the embodiment of the present invention may include the following contents:
S101:User writable instruction is received, and identifies the type of read write command.
User writable instruction includes that user reads data command and user written data instruction, namely reads message instruction and write message
Instruction.It can recognize that the operation of active user is read operation or write operation according to command information difference input by user.
S102:If the type of read write command is to write message instruction, the effective address number of the effective plane groups of solid state disk is obtained
Mesh, and multigroup user data to be written are written in nand flash memory simultaneously.
Effective plane groups are the normal plane of physical characteristic of storage medium, namely without damage, executable read-write behaviour
The plane groups of work.
After the multiple plane of system creation, it can instruct, data block in solid state disk is assigned to each previously according to grouping
In plane groups.For example, when there is n plane in some lun, the effective address of the first plane groups has m, then the group
Each data block of plane can be named as blockmn、blockmn+1、…、blockmn+n-1。
The effective address number of plane groups is the number of available block in the group.The group number of user's data to be written with
The number of effective address is identical, that is to say, that how many a, Ke Yitong of the number of the effective address of plane groups where current address
When the data of how many groups of numbers are written into nand flash memory.And the plane groups where the group number of data to be written is more than current address
Effective address number when, can be written in batches, which data is every batch of, which be all written, to randomly choose, also can be according to pre-establishing
LAB tables be determined, this does not influence the realization of the application.
For example, the number of the effective address of plane groups where current address is 5, and the group number of data to be written
Including 10, then 5 groups of data can be write at twice, every time to nand flash memory.
And when the number of the effective address of current address place plane groups is 0, current solid state disk may operation exception
Or be damaged, system can automatic feedback miscue information, to prompt user or staff to search and tie up as early as possible
It repaiies, reduces user's loss.
S103:If the type of read write command is to read message instruction, when meeting preset condition, then from nand flash memory
Data are read in cache.
Preset condition can be when a upper operation for current operation is read operation and address instructs corresponding address with message is read
Belong to same plane groups.
It, can be simultaneously for message is write based on multi-plane characteristics in technical solution provided in an embodiment of the present invention
The data to be written of user are written to nand flash memory, increase the data volume in write-once nand flash memory, when user has largely
When data are to be written, it can greatly reduce and write data time, improve the efficiency for writing data;For information is read, same plane is read
Group address in data when, the reading of data can be carried out directly in the caching of nand flash memory, without spend nand flash memory reading
Access evidence, improves data reading performance using redundancy, improves the hit rate of read buffer;By to being consolidated based on multi-plane characteristics
The reading/writing method of state hard disk optimizes, and is effectively improved the read and write rate of solid state disk, promotes the property of whole solid state disk
Can, and then enhance the competitiveness of solid state disk.
Based on above-described embodiment, present invention also provides another embodiments, referring to Fig. 2, specifically may include:
S201:Judge whether user writable instruction is to write message instruction, if so, executing S202;If it is not, then executing
S206。
S202:According to the available plane of reception instructions from each plane groups, effective plane groups are selected.
S203:Judge whether the number for the effective address for including in effective plane groups is not less than the group number of data to be written,
If so, S204 is executed, if it is not, then executing S205.
S204:Multigroup user data to be written are written in nand flash memory simultaneously.
S205:The data to be written of user are written in nand flash memory in batches.
S206:Judge whether to meet preset condition, if so, S207 is executed, if it is not, then executing S208.
Wherein, preset condition is when a upper operation for current operation is read operation and address instructs accordingly with message is read
Location belongs to same plane groups.
S207:Data are read from the cache of nand flash memory.
S208:Data are read from nand flash memory.
That is, when a upper operation for current operation is write operation, current read operation can only be from nand flash memory
It reads;When a upper operation for current operation is read operation, but read the address of the address and current read data of data
It is not belonging to the same plane, then current read operation can only be read from nand flash memory.
Information is read after reading data in nand flash memory, can further update last preserve, subsequently to use.
From the foregoing, it will be observed that the embodiment of the present invention is based on multi-plane, while operation is executed to multiple addresses, improves solid-state
The read and write rate of hard disk, and then promote the performance of whole solid state disk.
The embodiment of the present invention provides corresponding realization device also directed to the data read-write method of solid state disk, further makes
It obtains the method and has more practicability.It is situated between below to the data read-write equipment of solid state disk provided in an embodiment of the present invention
It continues, the data read-write method of the data read-write equipment of solid state disk described below and above-described solid state disk can be mutually right
It should refer to.

According to group number it is identical as the number of effective address.
Message optimisation module 303 is read, for being to read message instruction when the type of read write command, when meeting preset condition,
Then data are read from the cache of nand flash memory;Preset condition is when a upper operation for current operation is read operation and address
Belong to same plane groups with message instruction corresponding address is read.
In a kind of specific embodiment, the reading message optimisation module 303 can be when being unsatisfactory for preset condition, then
The module of data is read from nand flash memory.
