Please refer to fig. 1 and fig. 2, which are a first block diagram and a second block diagram of a storage device for fast updating firmware according to an embodiment of the present invention. As shown, a storage device 10 for fast updating firmware includes a first control unit 11, a second control unit 12, a wireless transmission unit 13 and a power switch unit 14. In the present embodiment, the storage device 10 may be a solid state disk, and the storage device 10 may be connected to a host 100 through a SATA flat cable and a power line. The first control unit 11 and the second control unit 12 may respectively comprise a microcontroller, and the wireless transmission unit 13 may comprise a bluetooth module. A power supply 101 of the host 100 is responsible for supplying a supply power 161 to the second control unit 12, the wireless transmission unit 13 and the power switch unit 14, and then the power switch unit 14 is responsible for transmitting the supply power 161 to the first control unit 11.
In a general case, the first control unit 11 is used for controlling data access to the flash memory on the memory device 10. Before the user wants to update the firmware 50 of the storage device 10, the user must first store the firmware 50 in the electronic device 200 having a bluetooth module, wherein the electronic device 200 may include a host computer, a notebook computer, or a workstation. It should be noted that the wireless transmission unit 13 of the present embodiment is implemented by taking a bluetooth module as an example, so the wireless transmission module on the electronic device 200 is also a bluetooth module, but not limited thereto, and other wireless transmission modules, such as a wireless network chip, an NFC chip, etc., may also be used for the two to achieve the function of transmitting the firmware 50.
When the user starts to update the firmware 50 of the storage device 10, the first control unit 11 can send an update signal 111 to the wireless transmission unit 13, and connect with the bluetooth module on the electronic device 200 through the wireless transmission unit 13, so as to receive the firmware 50 from the electronic device 200, and store the firmware 50 to a reserved location in the flash memory. When the reception is confirmed, the first control unit 11 transmits a first switching signal 112 to the second control unit 12. Then, the second control unit 12 controls the power switch unit 14 to block the supplied power 161 originally supplied to the first control unit 11, as shown in fig. 2, and after a certain period of time (about 2-3 seconds later), the power switch unit 14 conducts the supplied power 161 to the first control unit 11 again, so that the first control unit 11 starts to execute the firmware 50.
It is understood that the firmware update operation on the storage device 10 can be performed by an application program on the host 100, which can be executed by the application program to output a control signal to the first control unit 11 to trigger the firmware update operation, and the related art for executing the application program is well known in the art, and therefore will not be described herein.
From the above, the memory device 10 of the present invention can update the firmware without powering off and rebooting the host 100, thereby solving the existing problems in the prior art.

As shown, the storage device 10 for fast updating firmware of the present application may include a first control unit 11, a wireless transmission unit 13 and a power switch unit 14. In the present embodiment, the storage device 10 may be a solid state disk, and the storage device 10 may be connected to a host 100 through a SATA flat cable and a power line. The first control unit 11 may be a microcontroller, the wireless transmission unit 13 may include a bluetooth module, and a power supply 101 on the host 100 is responsible for supplying a supply power 161 from the host 100 to the power switch unit 14 and the wireless transmission unit 13. The first control unit 11 is electrically connected to the wireless transmission unit 13 and the power switch unit 14, and the first control unit 11 can only receive the supply power 161 through the power switch unit 14.
When the storage device 100 is updated with the firmware 50, the first control unit 11 can send an update signal 111 to the wireless transmission unit 13, and after the wireless transmission unit 13 receives the update signal 111, the wireless transmission unit 13 downloads the firmware 50 according to the update signal 111, wherein the firmware 50 is stored in a remote electronic device 200, and the electronic device 200 can be connected to the wireless transmission unit 13 via a bluetooth module, so as to transmit the firmware 50 from the electronic device 200 to the storage device 10.
After the wireless transmission unit 13 successfully downloads or receives the firmware 50, the wireless transmission unit 13 transmits a second switching signal 131 to the power switch unit 14 to drive the power switch unit 14 to block the supply of the power 161 to the first control unit 11, and the first control unit 11 is in a power-free state at this time, as shown in fig. 4. After a period of time, the wireless transmission unit 13 will transmit the second switching signal 131 to the power switch unit 14 again to drive the power switch unit 14 to conduct the supply power 161 to the first control unit 11 again, so that the first control unit 11 starts executing the firmware 50.
It should be noted that the wireless transmission unit 13 of the present application is implemented by a bluetooth module, but not limited thereto, and may also include a network transmission module or an NFC communication module, etc., but it should be understood that the wireless transmission unit 13 must be capable of being matched with a wireless transmission device of the electronic device 200 to perform the connection and the data transmission of the firmware 50.
In a preferred embodiment, the wireless transmission unit 13 can transmit the second switching signal 131 to the power switch unit 14 through a general purpose input/output pin (GPIO pin).

The first control unit 11 and the second control unit 12 may be a microcontroller, the wireless transmission unit 13 may include a bluetooth module, and the Reset circuit unit 15 may include a Reset IC (Reset IC). A power supply 101 of the host 100 is responsible for supplying a supply power 161 from the host 100 to the first control unit 11, the second control unit 12 and the reset power unit 15.
When a user wants to update the firmware of the storage device 10, the first control unit 11 first sends an update signal 111 to the wireless transmission unit 13 to drive the wireless transmission unit 13 to connect to a bluetooth module on the electronic device 200, and start downloading the firmware 50 from the electronic device 200.
When the first control unit 11 successfully downloads or receives the firmware 50, the first control unit 11 sends a reset signal 113 to the second control unit 12, and then the second control unit 12 drives the reset circuit unit 15 to restart the first control unit 11, thereby starting to execute the downloaded firmware 50.
For further explanation, please refer to fig. 6, which is a partial circuit diagram of a storage device for fast updating firmware according to a third embodiment of the present invention, and also refer to fig. 5. As shown, the Reset circuit unit 15 may be a Reset integrated circuit (Reset IC), and the first control unit 11 may be a microcontroller in the memory device 10, wherein the Reset circuit unit 15 is electrically connected to the first control unit 11.
