Description

[Technical field]

[0001] The present invention relates to a memory card reader with a built-in function of deleting and optimizing its own data. More specifically, the present invention relates to a memory card reader with a built-in function of deleting and optimizing its own data, which can select and execute the data deletion and optimization algorithm by itself without connecting to a computer, by adding a data deletion and optimization algorithm to the firmware of the memory card reader and adding a button to the case of the memory card reader, in order to delete or optimize data stored in the memory card. [Background technology]

[0002] Memory cards are widely used as storage devices for digital cameras, and have the same structure as solid-state drives (SSDs) for computers. They also have the same problems as SSDs for computers, and when used for a long time, unused junk data accumulates in the memory, causing the speed to gradually slow down. To solve this problem, computers periodically perform an optimization function called TRIM in the OS, but memory cards used in digital cameras have a different format from those used in computers, and the TRIM function cannot be used. For this reason, it has even occurred that high-quality images are taken with a digital camera and the image is interrupted. To solve this problem, a method has been used in which a memory card is connected to a computer via a memory card reader and all 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 via the computer's USB connection method, and depending on the capacity of the memory card, it takes a very long time, shortening the life of the memory card. For this reason, the relevant technical field is required to develop an easier and faster data deletion and optimization technology for memory cards.

[0003] Meanwhile, when the lifespan of a memory card falls below 50%, cell errors may occur and the writing speed may drop sharply, but it is difficult for users to estimate or confirm such remaining lifespan in advance. [Prior art documents] [Patent documents]

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

[0051] Referring first to FIG. 4, a memory card reader device 200 may be configured to provide an interface for accessing a memory card 10 .

[0052] The memory card 10 can then be inserted into and removed from the digital camera 30 and configured to contain a non-volatile memory element.

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

[0054] The detailed configuration of the memory card reader 200 will now be described.

[0055] First, the memory card reader device 200 may 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, a memory card information automatic 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 life calculation module 212, a memory card deletion / optimization count storage module 213, a memory card deletion / optimization count automatic storage control module 214, and a memory card replacement time alarm module 215.

[0056] The detailed configuration will be described below.

[0057] The host interface module 201 may be configured to interface with a host terminal 20 .

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

[0059] Display 203 can be configured to display memory card information and remaining life of memory card 10 .

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

[0061] Such memory card information can be specified and set by the user.

[0062] The input module 204 may be configured to input 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 may be configured as a separate button or the like in the memory card reader 200.

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

[0064] And the format execution module 205 can be configured to execute formatting on the memory card 10 according to 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] At this time, the format execution module 205 can be configured to perform formatting 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 storing general data.

[0066] The memory card information storage module 206 may 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 may store memory card information about a plurality of memory cards 10.

[0067] The memory card information automatic storage control module 207 can receive memory card information of the memory card 10 from the host terminal 20 via the interface of the host interface module 201, and control the received memory card information to be automatically stored in the memory card information storage area 12.

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

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

[0070] At this time, the optimization can be performed by various optimization algorithms, and can be selected from among several optimization algorithms.

[0071] For example, according to the so-called 3-pass method of the US Department of Defense (DoD), data is overwritten three or more times when it is deleted. The entire memory device 10 is written with 0, then with 1, and then with any character again. Users 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 data deletions / optimizations performed by the data deletion / optimization module 208 .

[0073] The automatic memory card recognition module 210 may be configured to automatically recognize the memory card information stored in the memory card information storage area 12 and the memory card deletion / optimization count stored in the memory card deletion / optimization count storage area 13 through an interface of the memory card interface module 202. Here, the memory card information and the memory card deletion / optimization count may be stored in advance in the corresponding areas by the memory card reader 200.

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

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

[0076] Here, if the memory card 10 is configured with an NVMe (non-volatile memory express) memory, the memory card remaining life automatic calculation module 212 can also be configured to extract data deletion and writing related information using an existing SMART (Self-Monitoring, Analysis and Reporting Technology) device and grasp the number of times data has been deleted / optimized on the memory card.

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

[0078] Here, if the storage method of the memory card 10 is SLC, the average number of times that data can be deleted is up to 100,000 times, if the storage method is MLC, the average number of times that data can be deleted is up to 10,000 times, and if the storage method is TLC, the average number of times that data can be deleted is up to 1,000 times.

[0079] As a result, the remaining life span of the memory card 10 can be automatically calculated by subtracting the final number of data deletions / optimizations from the average number of deletions possible according to the corresponding storage method of the memory card 10.

[0080] The memory card deletion / optimization count storage module 213 may be configured to store the final deletion / optimization count calculated by the memory card remaining life automatic calculation module 212 .

[0081] The memory card deletion / automation count automatic saving control module 214 can control the final deletion / optimization count saved in the memory card deletion / optimization count saving module 213 to be automatically saved in 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 time alarm module 215 may be configured to generate a replacement time alarm for the memory card 10 using the remaining life of the memory card 10 automatically calculated by the memory card remaining life automatic calculation module 212, and output the alarm via the display 203 or a speaker (not shown). For example, the memory card replacement time alarm module 215 may be preset to generate a replacement time alarm when the remaining life is 50% or less. When the remaining life is 50% or less, errors occur in many cells of the memory card 10, causing the writing speed to slow down exponentially, so it is preferable to generate a replacement time alarm when the remaining life is 50% or less.

[0083] If the memory card 10 cannot be replaced and the remaining life is 0, a 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] FIG. 5 is a block diagram of a memory card according to an embodiment of the present invention.

[0085] Referring to FIG. 5, a memory card 10 may be configured to include a data storage area 11, a memory card information storage area 12, and a memory card deletion / optimization count storage area 13.

[0086] The detailed configuration will be described below.

[0087] The data storage area 11 is an area in which data is stored.

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

[0089] The memory card deletion / optimization count storage area 13 is an area in which the memory card deletion / optimization count is stored.

[0090] Meanwhile, 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 the lock setting alarm is received, perform lock switching to disable access to the data storage area 11. That is, when the remaining life is 0 times, the digital camera 30 cannot access the data storage area 11 of the memory card 10, and an error message such as a memory device 10 recognition error can be output. Thus, the user can know that a memory device 10 that can no longer be used is installed, and can immediately replace it and use it.
