Background technology
SD card is a kind of storage card based on semiconductor flash memory technique, it is widely used in mancarried device and insertion
In formula system, SD card initially grows up on the basis of MMC (Multimedia Card) cards, can be realized with mmc card simultaneous
Hold.Holotype is all deferred in communication between MMC/SD and master control at present, i.e., instruction must be sent out by master control, after slave device receives
The pattern responded carries out communication interaction.However, storage card smoothly reads and writes the premise of data, it is that MMC/SD cards can be smoothly
Be fitted with master control, reach speed it is consistent with voltage parameter after, could successful match.
As memory card technologies continue to develop, the high speed storing card of various specifications is more and more universal.During practical application, often
Can be due to the update and replacement of storage card, and block at a high speed different with the matching voltage of generic card, and master control is not easy to upgrade, and easily goes out
Existing card storage and the incompatible situation of master control, the situation that master control is unable to identification memory card happen occasionally.
Invention content
The application provides a kind of method and system of identification memory card, to enhance the ability of identification memory card.
According in a first aspect, provide a kind of method of identification memory card in a kind of embodiment, including：S1. it sends and powers on finger
It enables, makes storage card standby；S2. the identification information of voltage of storage card is read；S3. the identification voltage that master control is equipped with is read
Information；S4. the identification information of voltage of storage card is matched with the identification information of voltage that master control is equipped with；If S5. successful match,
Then identify successfully storage card；If matching is unsuccessful, returns and perform step S1, can not matched still if circulating beyond preset times
Work(, then improve step S6；S6. master control transmission powers on instruction, makes storage card standby, and reads the identification of master control outfit
Voltage parameter in the identification information of voltage is revised as with identifying that the matched voltage of information of voltage is joined in storage card by information of voltage
Number；Return again to step S1.
According to second aspect, a kind of system of identification memory card is provided in a kind of embodiment, including master control and storage card；It deposits
The built-in identification information of voltage of card storage；Master control powers on instruction for sending, is in storage card and awaits orders equipped with identification information of voltage
State；It is additionally operable to match the identification information of voltage of storage card with the identification information of voltage that master control is equipped with, if successful match,
Then identify successfully storage card；If matching is unsuccessful, the voltage parameter itself being equipped in identification information of voltage is changed, which is joined
Number is revised as with identifying the matched voltage parameter of information of voltage in storage card.
The method and system of identification memory card according to above-described embodiment, due to being identified in information of voltage by changing master control
Voltage parameter so that the voltage parameter be revised as in storage card identify the matched voltage parameter of information of voltage, so as to make master
Control can identify the storage card that cannot be identified originally.This method is modified on identification protocol, is cut without increasing peripheral voltage
Circuit is changed, the storage card of different voltages parameter can also be normally identified, save cost.
Description of the drawings
Fig. 1 is the method flow diagram of identification memory card of the present invention；
