4 is a flow chart of a host system automatically operating an application stored in an external memory storage device according to an exemplary embodiment of the invention.

Referring to FIG. 4, when the external memory storage device 100 is coupled to the host system 1100, the host system 1100 actively requests the external memory storage device 100 to transmit the current operation mode of the selection switch 108 in step S401. For example, the boot program 1124 capable of transmitting the command for requesting the selection flag is previously operated in the operating system of the host system 1100, and when the user couples the external memory storage device 100 to the host system 1100. The pilot program 1124 will issue an instruction to the external memory storage device 100 for requesting the selection flag. And, upon receiving an instruction to request the selection flag, the memory management circuit 202 of the memory controller 104 transmits the stored selection flag to the vector 1124. For example, when the selection switch 108 is in the first position, the memory management circuit 202 transmits a selection flag labeled as the first mode of operation to the pilot program 1124, and when the selection switch 108 is in the second position, the memory control The selector 104 transmits a selection flag labeled as the second mode of operation to the pilot 1124.

Thereafter, in step S403, the host system 1100 executes one of the stored applications in accordance with the current mode of operation of the selection switch 108. For example, when a selection flag is received, the navigation program 1124 will run the application stored in the memory module 106 in accordance with the flag of the selection flag. Specifically, the daemon 1124 runs the first application 182 in the operating system 1122 when a selection flag labeled the first mode of operation is received. And, when receiving the selection flag labeled as the second mode of operation, the pilot program 1124 runs the second application 184 in the operating system 1122.

It is worth mentioning that the pilot program 1124 periodically polls the memory storage device 100 for the selection flag to identify whether the state of the selection flag has been changed. For example, at intervals (e.g., 5 seconds), the pilot program 1124 issues an instruction to request the selection flag to the memory storage device 100.

In addition, in another exemplary embodiment of the present invention, the boot program 1124 detects that the memory storage device 100 is recoupled to the host system 1100 (ie, the memory storage device 100 is disconnected from the host system 1100). When the electrical connection is again electrically connected to the host system 1100), the pilot program 1124 again issues an instruction for requesting the selection flag to the memory storage device 100.

It is worth mentioning that when the state of the selection flag is changed, the guide program 1124 will execute the corresponding application according to the state of the selection flag.

For example, assuming that the memory storage device 100 is coupled to the host system 1100 in a state where the position of the selection switch 108 is positioned at the first position, the guidance program 1124 operates in the operating system 1122 according to the received selection flag. The first application 182. At this time, if the user sets the position of the selection switch 108 to the second position, since the flag of the selection flag has been changed to the second operation mode, the guidance program 1124 will be in the operating system 1122 according to the received selection flag. The second application 184 is run. That is, in this example, both the first application 182 and the second application 184 will be run in the operating system 1122.

It is worth mentioning that, in addition to running a plurality of applications stored in the external memory storage device 100 at the same time, in another exemplary embodiment of the present invention, the guiding program 1124 can also only have one of the applications at the same time. Being operated. For example, in another exemplary embodiment of the present invention, when the user sets the position of the selection switch 108 to the second position, the guiding program 1124 first determines the first in the operating system 1122 before running the second application 184. Whether the application 182 has been run. Moreover, when the first application 182 has been run, the boot program 1124 terminates the operation of the first application 182 and then runs the second application 184. On the other hand, when the user sets the position of the selection switch 108 to the first position, the guiding program 1124 determines whether the second application 184 has been operated in the operating system 1122 before running the first application 182. Moreover, when the second application 184 has been run, the navigation program 1124 terminates the operation of the second application 184 and then runs the first application 182.

In the present exemplary embodiment, the pilot program 1124 that is pre-running on the host system 1100 is pre-stored in the built-in storage device 1120. However, the invention is not limited thereto. For example, in another exemplary embodiment of the present invention, the navigation program 1124 and the automatic execution file for automatically running the navigation program 1124 (for example, a script file named "Autorun.inf") will It is stored in the partition 180 of the memory module 106, and the memory controller 104 simulates the partition as a disc partition.

That is, when the user couples the memory storage device 100 to the host system 1100 and the host system 1100 queries the external memory storage device 100 for its media feature, the memory management circuit 202 will announce the segmentation to the host system 1100. The area 180 is a disc division area. Thereafter, the operating system 1122 automatically operates the automatic execution file stored in the partition 180, and the operated automatic execution file automatically runs the guidance program 1124 in the operating system 1122. Therefore, in this exemplary embodiment, the navigation program 1124 need not be stored in the built-in storage device 1120 in advance.

The host interface 204 is coupled to the memory management circuit 202 and is configured to receive and identify instructions and data transmitted by the host system 1100. That is to say, the instructions and data transmitted by the host system 1100 are transmitted to the memory management circuit 202 through the host interface 204. In the exemplary embodiment, the host interface 204 is a USB interface of the corresponding connector 102. However, it must be understood that the present invention is not limited thereto, and the host interface 204 may be other suitable plug and play data transmission interfaces.

The memory interface 206 is coupled to the memory management circuit 202 and used to access the memory module 106. That is, the data to be written to the memory module 106 is converted to a format acceptable to the memory module 106 via the memory interface 206.

In an exemplary embodiment of the invention, the memory controller 104 further includes a buffer memory 252. The buffer memory 252 is coupled to the memory management circuit 202 and is used to temporarily store data and instructions from the host system 1100 or data from the memory module 106. For example, the selection flag described above will be stored in the buffer memory 252.

In an exemplary embodiment of the invention, the memory controller 104 further includes a power management circuit 254. The power management circuit 254 is coupled to the memory management circuit 202 and is used to control the power of the external memory storage device 100.

In an exemplary embodiment of the invention, the memory controller 104 further includes an error checking and correction circuit 256. The error checking and correction circuit 256 is coupled to the memory management circuit 202 and is used to perform an error checking and correction procedure to ensure the correctness of the data. Specifically, when the memory management circuit 202 receives a write command from the host system 1100, the error check and correction circuit 256 generates a corresponding error check and correction code for the data corresponding to the write command (Error Checking and Correcting). Code, ECC Code), and the memory management circuit 202 writes the data corresponding to the write command and the corresponding error check and correction code into the memory module 106. After that, when the memory management circuit 202 reads the data from the memory module 106, the error check and correction code corresponding to the data is simultaneously read, and the error check and correction circuit 256 checks the error check and the correction code according to the error check and correction code. The read data performs an error correction procedure.

Referring to FIG. 5, step S501 is to arrange a selection switch 108 that can be set in one of a plurality of operation modes in the external memory storage device 100. Here, the number of modes of operation of the selection switch 108 may depend on the number of applications to be stored in the memory storage device 100, wherein each mode of operation will correspond to one of the applications.

Step S503 is to run the navigation program 1124 in the operating system 1122 of the host system 1100. Thereafter, step S505 is to couple the external memory storage device 100 to the host system 1100. It is worth mentioning that in the example where the boot program 1124 is stored in the analog disc partition of the external storage device 1000, the boot program 1124 is only after the external memory storage device 100 is coupled to the host system 1100. It is operated in the operating system 1122.

In step S507, the memory controller 204 detects the current mode of operation in which the selection switch 108 is located and marks the selection flag as the current mode of operation. The manner of marking the selection flag has been described above, and the description will not be repeated here.

Thereafter, in step S509, the navigation program 1124 requests the selection memory from the external memory storage device and receives the selection flag from the memory controller 204.

Then, in step S511, the pilot program 1124 runs the corresponding application in the operating system 1122 according to the received selection flag. The manner in which the corresponding application is run according to the operation mode marked by the selection flag has been described above, and the description will not be repeated here.

It should be understood that, although not shown in the drawings, in another exemplary embodiment of the present invention, the application execution method further includes periodically requesting a selection flag or detecting a memory storage device from the memory storage device 100. When 100 is recoupled to the host system 1100, the selection flag is again requested to the memory storage device 100, and the corresponding application stored in the memory storage device 100 is operated according to the change of the flag.
