1273405 發明說明(1) 【發明所屬之技術領域] 本發明係關於一種防止記憶卡被寫入之方法及電子裝 置,尤指在一電子裝置上安裝一防寫軟體,以藉該防寫軟 體所提供之一防寫對照表,使得該電子裝置之插槽,可處 於一防寫狀態或一可寫入狀態。 ~ 【先前技術】 按,近年來,由於電子、電腦科技及生產、製造與材 料技術的日新月異,使得一般消費性等級的數位電子產 0¾ ’亦可具有極高的效果與品質,且透過成本降低、體積 縮小及重量減輕等發展趨勢,使得該等數位電子產品廣為 大眾所接受,例如:數位相機(Digital Camera,DC)、 數位攝影機(Digital Video,DV)、個人數位助理機 (Personal Digital Assistant,PDA) 、MP3 音樂播放器 (Mpeg layer 3 Player,MP3 Player)或全球衛星定位 系統(Global Position System,GPS)等。一般傳統之 數位電子產品之資料,例如:音樂、影像或導航用地圖 等,大多係儲存於該等數位電子產品所内建之一固定式記 應隱元件(如··快閃記憶體(nash Memory ))中,該固定 式記憶元件係可提供一固定容量之記憶體空間,以儲存該 等資料及令該數位電子產品正常運作所需之軟體。 然而,由於該等數位電子產品的製造廠商,經由不斷 地研究與開發,而設計、製造出許多更具優良效果與品質 之數位電子產品,致使該等數位電子產品需要更大的記憶1273405 Description of the Invention (1) Technical Field of the Invention The present invention relates to a method and an electronic device for preventing a memory card from being written, and more particularly to installing an anti-writing software on an electronic device for borrowing the software. An anti-write comparison table is provided such that the slot of the electronic device can be in a write-protected state or a writable state. ~ [Prior Art] In recent years, due to the rapid development of electronics, computer technology and production, manufacturing and materials technology, the digital electronic products of general consumer grades can also have extremely high effects and quality, and the cost is reduced. Trends such as volume reduction and weight reduction have made these digital electronic products widely accepted, such as digital cameras (Digital Cameras, DC), digital video cameras (DV), personal digital assistants (Personal Digital Assistant). , PDA), MP3 music player (Mpeg layer 3 Player, MP3 Player) or Global Positioning System (GPS). The data of traditional digital electronic products, such as music, video or navigation maps, are mostly stored in the digital electronic products built into a fixed type of hidden components (such as · flash memory (nash) In the memory), the fixed memory component provides a fixed-capacity memory space for storing the data and the software required for the digital electronic product to function properly. However, as these digital electronic product manufacturers continue to research and develop, they have designed and manufactured many digital products with better effects and quality, which makes these digital products require more memory.

Description of invention (2) Body space can store the high quality required (or called Gaole or map, etc.) This action causes the use of the general tradition to use it. Because & The manufacturer's product: "Lv Ji recall card" was developed, for example, Compact Flash Card (CF Card) or Multimedia Media Card (MMC), etc. = thin, cheap, easy to carry and large capacity, and m-bit electronic products, free to change freely 'to make these digital power; on the production port, the memory space for storing data can be expanded indefinitely. > In addition, these memory cards can also be used to replace the conventional traditional floppy disk. A user of the memory card can be on a host computer (such as a personal computer (Personal Computer 'PC) or a personal digital assistant (Personal Digital) On the Assistant, PDA, etc., data such as reports, jobs, etc. are stored on the memory card, and after the memory card is inserted into another host, the data in the memory card can be transferred to another host. And can carry such information with you Or the purpose of transferring the data to another host, etc., therefore, by virtue of the advantages described above, the memory cards are pushed into the market, which is favored by the public. The card can be inserted on different hosts, so that the data on the host can easily cover the original data in the memory card. Therefore, the conventional memory card has an anti-write switch, and the anti-write switch is provided. The relationship can be used to protect the data in the memory card, and when the anti-write switch is toggled, the memory card can be made in a write-protected state or a writable state.

Invention Description (4) Table, the anti-write check table is one of the anti-write barrier slots (such as D, the anti-write option is in a write-protected state. When the electronic device is placed on the memory card, the anti-writing body is in the memory card, and is generated in a write-protected state. The item is not selected or taken in the slot, and the data can be stored in the device, etc., The anti-writing software can provide an anti-wolf pair with at least an information field, and corresponding to the 'location, Wherein, the information field is used to store the slot slot, and the anti-write block has an anti-write option selected to enable the slot corresponding to the anti-write option, and another object of the present invention. When a user wants to store data to a memory card inserted in the slot to control the electronic device, the data is prohibited from being transmitted to the error signal, so that the user knows that the slot is another one of the inventions. The purpose is to write the corresponding anti-write option in the state of the anti-write selection point, and the user inserts the electronic device into the memory card of the slot. The review committee can perform the matching feature and its function, and make a more detailed diagram. The following is a detailed description of the purpose, shape, and structure of the present invention. Embodiments [Embodiment] ^ The present invention is a The method and the electronic device for preventing the memory card from being written" 'Please refer to the figure 1 and 2' to install an anti-write software 20 on an electronic device 1 '. The anti-writing software 20 can provide an anti-write pair Zhao, two anti-write comparison table 21 has at least one capital Field 22 (or slot 31 field), and an anti-write block 23 corresponding to the information block 22, the capital 1273405 5, the invention description (5) in the field 22, can be stored in the electronic Install slot 31 (such as: D slot or F, 々 * U sighs) a slot 30 and the anti-write block 23, 々 disk player serial number and other related information, select to select Library:, =: an anti-write option 24, for the user to point or write state: Borrow: = 2 should be 4 slots 30 is in the anti-write state 兮 ρ yiyi, $馆 9/1 + 匕 * violation When the anti-write option 24 is selected, the slot 3 of the anti-write far item 24 is opposite to the write option 24, which is not selected by the write option 24, or is: anti-write heart, and the defense 24 If the slot is 3〇, it can be in the writable state. The anti-write option is set to - when the electronic device 1 is activated, please refer to the "No" and "3". ;* |Wanma software 2〇 is carried out according to the following steps. (101) 'First 'read the electronic device 1Q, the slot 3 〇 slot d 1 , (102) 嗣, the The slot 31 is stored in the information block 22; (1 0 3 )硐, the anti-write pair is analyzed According to Table 2, the content of the anti-write block 23 is blocked by the information block 22; after the w is 3, it has been clicked on the anti-write #30 lj 4 )硐' to determine the anti-write option in the anti-write block 2 3 2 4 whether it is farther than 1 if the slot 30 corresponding to the anti-write option 24 is sorrowful, that is, it ends, otherwise, the corresponding to the anti-write option 24 is in a writable state, and then ends. . As shown in Figures 1, 2 and 5, the slot 3 can be used to insert an L card 32 (such as a compact flash memory card (c々mpact Fiash Card, CF C々ard) or multimedia). A memory card (Mulu Media Car (1, MMC), etc.) is provided to provide a memory space for storage to be utilized by the electronic device
