Description of drawings

Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, and illustrative examples of the present utility model and explanation thereof are used to explain the utility model, do not constitute improper qualification of the present utility model.In the accompanying drawings:

Fig. 1 is the block scheme of the Ssd apparatus (memory storage) according to embodiment of the present utility model.

Embodiment

Below with reference to accompanying drawing, describe embodiment of the present utility model in detail.

Fig. 1 is the functional block diagram according to the Ssd apparatus of embodiment of the present utility model.As shown in Figure 1, has the Ssd apparatus 100 of supporting feedback user mode function, comprise: solid state hard disc (promptly first memory module also is the storage of subscriber data module) 101, state parameter memory module 102, control module 104, read module 105 and output module 106.

Below, will describe the implementation of Ssd apparatus and its user mode of support feedback thereof with reference to figure 1 in detail.Wherein, should be appreciated that solid state hard disc is carried out after, always it to write indegree (for example 1000 times) just fixing, it is also just fixing always to write data volume, for the solid state hard disc of 32GB, is exactly 32x1000x10000B.

Data volume that state parameter memory module 102 storage accumulative total in the Ssd apparatus 100 writes and control module 104 are upgraded the data volume that this accumulative total writes based on the user to the read-write operation of Ssd apparatus 100.The control module 104 of Ssd apparatus 100 can comprise specifically that a statistics module (not shown) adds up the mean value that the user writes data volume every day, and this mean value is stored in the state-storage module 102.104 pairs of accumulative totals that are stored in the state parameter memory module 102 of the control module of Ssd apparatus 100 write that data volume reads and carry out following formula and calculate:

Residual life number percent=(always writing the data volume that data volume-accumulative total writes)/always write data volume ... ... ... ... ... ... ... ... (1)

And/or

Remain and on average write data volume pot life=(always writing the data volume that data volume-accumulative total writes)/every day ... ... ... ... ... ... ... (2)

Therefore, finish whole statistical computation, and be stored in the state parameter memory module 102, thereby even this statistics can not lost under power-down conditions yet by control module 104.

Read module 105 is connected with state parameter memory module 102, be used to read wherein each state parameter of storage, comprise and always write data volume, add up the data volume that writes and on average write data volume (unit interval on average writes data volume), and according to these life parameters that calculates, for example above-mentioned residual life number percent and residue pot life.If only need calculate residual life number percent, can not comprise in the state parameter that then the unit interval on average writes data volume.

Next, by output module 106 this statistics is outputed to the outside.Wherein, output module 106 can utilize multiple mode that lifetime data is read.For example, utilize existing smart interface.Present SATA, SCSI, hard-disk interfaces such as IDE are all supported the smart access technique, (Self-Monitoring Analysis and Reporting Technology, monitor certainly, analysis and reporting techniques).This in time can monitor comprising hard disk parts such as magnetic head, disc, motor, circuit, by the monitoring of software on testing circuit and the main frame monitored target is detected, its operation conditions and historical record are analyzed, compared with default safety value, when the scope that has exceeded safety value, can give a warning from the trend user, and then the hard disk incipient fault made effective prediction, improved the security of data storage.S.M.A.R.T information is retained in the service area (service area) of hard disk, and this zone generally is positioned at tens physical tracks in foremost of hard disk 0 physical surface, writes the associated inner supervisory routine by manufacturer.Except the S.M.A.R.T information table, also comprise low-level formatting program, encrypting and decrypting program, from watchdog routine, repair procedure etc. automatically.(command code is: B0h) S.M.A.R.T information is read, and do not allow the final user that information is made amendment in the order of monitoring of software by one by name " SMART RETURN STATUS ".

Can in S.M.A.R.T information, add some again, be used for feeding back the life-span of SSD hard disk.Such as remaining life-span number percent, the data volume that accumulative total writes etc.Perhaps, increase new interface,, finish the work of data transmission such as I2C.

Above-mentioned Ssd apparatus 100 can be further used in the electronic equipment such as computing machine.At this moment, first memory module just is provided in a side of the solid state hard disc in the computing machine, and the storage output module is the display device of computing machine, is used to show the state parameter of memory storage, the residual life situation that can present like this, Ssd apparatus 100 intuitively to the user.

Therefore, finish whole statistical computation, and result of calculation is exported to show the behaviour in service of hard disk to the user by the appropriate section of computing machine.

The above is a preferred embodiment of the present utility model only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
