Background Art

[0002] Memory cards are mainly widely used as storage devices for digital cameras. They have the same structure as SSDs (Solid-State Drives) for computers and also have the same problems as general SSDs. If used for a long time, there is a disadvantage that garbage data not used in the memory accumulates and the speed gradually becomes slower. To solve such problems, computers perform an optimization function called TRIM periodically in the OS. However, in the case of memory cards used in digital cameras, the format is different from that for computers and the TRIM function cannot be used. For this reason, even when shooting high-quality videos with a digital camera, shooting may be interrupted. To solve this problem, a method has been used in which the memory card is connected to a computer via a memory card reader device and all the data remaining on the memory card is deleted using a program called Low Format. However, this method has the disadvantage that data is transmitted to the memory card reader device via the computer's USB connection method, which takes a very long time depending on the capacity of the memory card and shortens the life of the memory card. Therefore, in this technical field, the development of an easier and faster data deletion and optimization technology for memory cards is required.

[0003] On the other hand, when a memory card's lifespan drops below 50%, errors may occur in the cells or the write speed may decrease sharply, but it is not easy for users to estimate or check this remaining lifespan in advance. [Prior art documents] [Patent Documents]

[0035] Figure 1 is a perspective view of a memory card reader device incorporating a self-data deletion and optimization function according to one embodiment of the present invention.

[0036] Referring to Figure 1, in the first step, the memory card that requires data deletion and optimization is inserted into a memory card reader that has a built-in data deletion and optimization function.

[0037] In the next step, the user clicks a button on the memory card reader, which has a built-in data deletion and optimization function, to select the algorithm required for data deletion or optimization.

[0039] Figure 2 is a block diagram of a memory card reader device with built-in self-data deletion and optimization functions according to the first embodiment of the present invention.

[0040] Referring to Figure 2, the present invention comprises a memory card connection unit 110 that electrically connects a memory card and a processor unit 130, a button unit 120 that selects a delete and optimize algorithm and transmits an execution command to the processor unit 130, a status display unit 140 that displays the algorithm and operating status selected by the button unit 120, a processor unit 130 that deletes or optimizes data stored on the memory card connected to the memory card connection unit 110 using the algorithm selected by the button unit 120, and a computer connection unit 150 that connects the memory card and a computer via the processor unit 130.

[0041] The memory card connector 110 electrically connects the memory card and the processor unit 130.

[0042] The button unit 120 is electrically connected to the processor unit 130 so that the processor unit 130 can sense whether or not the button has been pressed. The button unit 120 can consist of multiple buttons for the processor unit 130 to select which button to press.

[0043] The status display unit 140 is electrically connected to the processor unit 130 and displays the signals output by the processor unit 130 on an LED or LCD screen.

[0044] The computer connection unit 150 is electrically connected to the processor unit 130.

[0045] The processor unit 130 periodically searches the memory card connection unit 110 and the button unit 120 to confirm whether a memory card is connected and whether the button on the button unit 120 has been pressed. It then outputs the algorithm and operating status selected by the user according to a predetermined rule to the status display unit 140. When an execution command is detected via the button unit 120, the processor unit 130 modifies the contents of the memory card inserted in the memory card connection unit 110 using the selected algorithm. The processor unit 130 also periodically searches the computer connection unit 150 and, according to the instructions of the connected computer, connects the memory card inserted in the memory card connection unit 110 to the computer so that the computer can directly read and write to the memory card.

[0046] Figure 3 is a flowchart showing the operation method of a memory card reader with built-in self-data deletion and optimization functions according to one embodiment of the present invention.

[0047] Referring to Figures 2 and 3, the processor unit 130 of the memory card reader 100, which has a built-in self-data deletion and optimization function, periodically searches the memory card connection unit 110, the button unit 120, and the computer connection unit 150 to confirm whether a memory card is connected, whether a button has been pressed, and whether it is connected to the computer. It then completes the work according to the prescribed rules and displays the status on the status display unit 140, repeating this process (S210).

[0048] If the pressed state of the button unit 120 corresponds to a data deletion and optimization execution command, the processor unit 130 modifies the data on the memory card according to a predetermined algorithm (S240).

[0049] The processor unit 130 can connect or disconnect the computer and the memory card according to the instructions of the computer connected to the computer connection unit 150 (S270).

[0050] Figure 4 is a block diagram of a memory card reader equipped with a data optimization function and a life prediction function, with a life display function added, according to a second embodiment of the present invention.

[0051] First, referring to Figure 4, the memory card reader 200 can be configured to perform interfacing for accessing the memory card 10.

[0052] The memory card 10 can be attached to and detached from the digital camera 30 and can be configured to include non-volatile memory elements.

[0053] The host terminal 20 can be configured to access the memory card 10 via a memory card reader 200. For example, the host terminal 20 can be a laptop computer, a PC, or the like.

[0054] The following describes the detailed configuration of the Memory Card Reader Unit 200.

[0055] First, the memory card reader unit 200 can be configured to include a host interface module 201, a memory card interface module 202, a display 203, an input module 204, a format execution module 205, a memory card information storage module 206, an automatic memory card information storage control module 207, a data deletion / optimization module 208, a data deletion / optimization count module 209, an automatic memory card recognition module 210, an automatic memory card identification module 211, an automatic memory card remaining lifespan calculation module 212, a memory card deletion / optimization count storage module 213, an automatic memory card deletion / optimization count storage control module 214, and a memory card replacement timing alarm module 215.

[0056] The following explains the detailed structure.

[0057] The host interface module 201 can be configured to interface with the host terminal 20.

[0058] The memory card interface module 202 can be configured to interface with the memory card 10.

[0059] The display 203 can be configured to display memory card information and remaining lifespan of the memory card 10.

[0060] Here, the memory card information can be configured to include the identifier, purpose, and storage method of the memory card 10. The identifier is a configuration for identifying the memory card 10 and can be an ID, name, distinction number, etc. The purpose is a configuration related to whether it is for general data authorship or for use with a digital camera 30. The storage method can be one of the following for the memory card 10: SLC (single level cell), MLC (multi-level cell), or TLC (triple level cell).

[0061] This type of memory card information can be specified and set by the user.

[0062] The input module 204 can be configured to receive a memory card format command for formatting the memory card 10 or a memory card delete / optimize command for deleting / optimizing the memory card 10. The input module 204 can be configured as a separate button or the like on the memory card reader 200.

[0063] The format execution module 205 can be configured to receive memory card format commands from the host terminal 20 via the interface of the host interface module 201.

[0064] The format execution module 205 can be configured to perform formatting on the memory card 10 in accordance with a memory card format command received via the host interface module 201 or a memory card format command input via the input module 204.

[0065] In this case, the format execution module 205 can be configured to execute formatting of the memory card 10 by separately specifying a memory card information storage area 12 for storing memory card information and a memory card deletion / optimization count storage area 13 for storing the number of times the memory card has been deleted / optimized, in addition to the data storage area 11 for general data storage.

[0066] The memory card information storage module 206 can be configured to receive and store memory card information from the host terminal 20 via the interface of the host interface module 201. The memory card information storage module 206 can store memory card information for a number of memory cards 10.

[0067] The memory card information automatic saving control module 207 can receive memory card information from the host terminal 20 via the interface of the host interface module 201 and control the module to automatically save the received memory card information to the memory card information storage area 12.

[0068] The data deletion / optimization module 208 can be configured to receive memory card deletion / optimization commands from the host terminal 20 via the interface of the host interface module 201.

[0069] The data deletion / optimization module 208 can be configured to delete and optimize data stored in the data storage area 11 in accordance with the memory card deletion / optimization command it receives, or a memory card deletion / optimization command input via the input module 204.

[0070] In this case, optimization can be performed using a variety of optimization algorithms, and a selection of several optimization algorithms can be used.

[0071] For example, the so-called 3-pass method of the U.S. Department of Defense (DoD) involves overwriting data three or more times when deleting it. The entire memory element 10 is written with zeros, then with ones, and then again with arbitrary characters. The user can select and use the most suitable deletion / optimization algorithm as needed.

[0072] The data deletion / optimization count module 209 can be configured to count the number of times data deletion / optimization has been performed by the data deletion / optimization module 208.

[0073] The memory card automatic recognition module 210 can be configured to automatically recognize memory card information stored in the memory card information storage area 12 and the number of memory card deletions / optimizations stored in the memory card deletion / optimization count storage area 13 via the interface of the memory card interface module 202. Here, the memory card information and the number of memory card deletions / optimizations can be pre-stored in the corresponding areas by the memory card reader device 200.

[0074] The memory card automatic identification module 211 can be configured to automatically identify the memory card 10 by searching for the memory card information automatically recognized by the memory card automatic recognition module 210 against the memory card information stored in the memory card information storage module 206. The memory card automatic identification module 211 can identify the corresponding memory card 10 using an identifier from the memory card information.

[0075] The memory card remaining lifespan automatic calculation module 212 can be configured to calculate the final data deletion / optimization count by adding the data deletion / optimization count counted by the data deletion / optimization count module 209 to the deletion / optimization count count automatically recognized by the memory card automatic recognition module 210.

[0076] In this case, if the memory card 10 is composed of NVMe (non-volatile memory express) memory, the memory card remaining lifespan automatic calculation module 212 can also be configured to extract data deletion and write-related information from an existing SMART (Self-Monitoring, Analysis and Reporting Technology) device to determine the number of data deletions / optimizations of the memory card.

[0077] The memory card remaining lifespan automatic calculation module 212 can be configured to automatically calculate the remaining lifespan of the memory card 10 based on the number of data deletions / optimizations, by referring to the storage method stored in the memory card information storage module 206, and output this calculation via the display 203.

[0078] Here, if the memory card 10 uses SLC storage, it can be deleted on average up to 100,000 times; if it uses MLC storage, it can be deleted on average up to 10,000 times; and if it uses TLC storage, it can be deleted on average up to 1,000 times.

[0079] This allows the remaining lifespan to be automatically calculated by subtracting the final data deletion / optimization cycle from the average number of deletions possible for the memory card 10 using the relevant storage method.

[0080] The memory card delete / optimization count saving module 213 can be configured to save the final delete / optimization count calculated by the memory card remaining lifespan automatic calculation module 212.

[0081] The memory card deletion / automation count automatic saving control module 214 can control the automatic saving of the last deletion / optimization count stored in the memory card deletion / optimization count saving module 213 to the memory card deletion / optimization count area 13 of the memory card 10 via an interface with the memory card interface module 202.

[0082] The memory card replacement alarm module 215 can be configured to generate a replacement alarm for the memory card 10 using the remaining lifespan of the memory card 10 automatically calculated by the memory card remaining lifespan automatic calculation module 212, and output it via the display 203 or speaker (not shown). For example, the memory card replacement alarm module 215 can be pre-configured to generate a replacement alarm when the remaining lifespan is 50% or less. When the remaining lifespan is 50% or less, errors occur in many cells of the memory card 10, causing the write speed to slow down geometrically, so it is preferable to generate a replacement alarm when the remaining lifespan falls below 50%.

[0083] Furthermore, if the memory card 10 cannot be replaced and the remaining lifespan is 0, the memory card lock setting alarm module (not shown) can be configured to generate a lock setting alarm and send it to the memory card 10 via the memory card interface module 202.

[0084] Figure 5 is a block diagram of a memory card according to one embodiment of the present invention.

[0085] Referring to Figure 5, the memory card 10 can be configured to include a data storage area 11, a memory card information storage area 12, and a memory card delete / optimization count storage area 13.

[0086] The following explains the detailed structure.

[0087] The data storage area 11 is the area where data is stored.

[0088] The memory card information storage area 12 is the area where memory card information is stored.

[0089] The memory card delete / optimization count storage area 13 is the area where the number of times the memory card has been deleted / optimized is stored.

[0090] On the other hand, the memory card lock setting unit (not shown) of the memory card 10 can be configured to receive a lock setting alarm via the memory card interface module 202, and when a lock setting alarm is received, to perform lock switching to make access to the data storage area 11 impossible. That is, if the remaining lifespan is 0, the digital camera 30 will not be able to access the data storage area 11 of the memory card 10, and an error message such as a memory element 10 recognition error may be output. In this way, the user will know that a memory element 10 that can no longer be used is installed and can immediately replace it.
