SanDisk公司于2000年4月公布的“多媒体卡产品手册”(版本2)中说明了这些产品,该手册特地收录在此作为本文的参考文献。 SanDisk Corporation in April 2000 released "Multimedia Card Product Guide" (version 2) is described in these products, which specifically included in this manual are incorporated herein by reference. MMC产品的电气操作的某些方面还在转让给SanDisk公司的皆于1998年11 月4 日由N.Toombs和Micky Holtzman提出的序号为09/185,649和09/186,064的待审专利申请中说明。 Certain aspects of the electrical operation of the MMC products also assigned to SanDisk's numbers are on November 4, 1998 by the N.Toombs and Micky Holtzman proposed 09 / 185,649 and 09 / 186,064 pending patent application instructions. 在转让给SanDi sk公司的美国6,040,622号专利中说明了卡的物理结构以及一种制造它的方法。 Assigned to the SanDi sk's US Patent No. 6,040,622 describes the physical card structure and a method of manufacturing it. 这些申请以及该专利也特地收录在此作为本文的参考文献。 These applications and patents are also specifically included herein by reference herein.

[0004]较新的SD卡类似于MMC卡,二者尺寸相同但SD卡厚度增加以容纳一块附加的存储器芯片。 [0004] The newer SD Card is similar to MMC card, SD card both the same size but increase in thickness to accommodate an additional memory chip. 它们之间的主要区别在于,SD卡含有附加的数据接点组以便能在卡和主机之间更快地传送数据。 The main difference between them is that, SD card containing the contact group so that additional data can transfer data faster between the card and the host. SD卡的其它接点和MMC卡的接点相同,以便使设计成接受SD卡的插口也接受MMC卡。 The same contacts and other contacts of the SD card, MMC card, so that is designed to accept the SD card socket also accepts MMC card. SD卡的电气接口还基本上做成向后和前面引用的该规范的2.11版本中所说明的MMC产品兼容,以便为了容纳这二种类型的卡只需要对主机操作做出很少的改变。 MMC products SD card electrical interface is also backwards and basically made the specification cited above as described in version 2.11 is compatible, so in order to accommodate these two types of cards only need to make a few changes in the host operating.

[0005] 根据IS0/IEC7816标准做成的卡与MMC卡以及SD卡形状不同,表面接点位于不同位置并且电气接口不同。 [0005] According to IS0 / IEC7816 standard made of card and MMC cards and SD cards of different shapes, the contact surface at different positions and different electrical interface. ISO/1EC 7816标准具有“识别卡-带有接点的集成电路(组)卡”的概括标题并且由分别带有从1994年到2000年的日期的1-10部分组成。 ISO / 1EC 7816 standard with the "Identification cards - Integrated circuit with contacts (group) Card" summarized by the title and composition respectively with Part 1-10 from 1994 to 2000 dates. 可以从端士日内瓦的IS0/IEC得到其拷贝的该标准特地收录在此作为本文的参考文献。 Guests from the end of the Geneva IS0 / IEC standard to obtain a copy of the specially included herein by reference herein. IS0/IEC 7816卡尤其在必须安全地存储数据从而在未经授权情况下极难或者不可能读出该数据的应用中是有用的。 IS0 / IEC 7816 cards are especially data must be securely stored so difficult in the case of unauthorized use or impossible to read this data is useful.

[0006]小型IS0/IEC 7816卡的一种通常使用是在电子系统中防止盗窃和/或未授权使用,在这种情况下该卡存储对用户或者对电子系统专用的安全代码。 A common use of [0006] Small IS0 / IEC 7816 card in an electronic system to prevent theft and / or unauthorized use, in which case the memory card to the user or the electronic system-specific security code. 例如,安装在车辆中的无线电设备是一种类型的电子系统,其中要使该设备工作时需要输入对该无线电设备专用的安全代码。 For example, the radio equipment installed in a vehicle is a type of electronic systems, which enable the device to work when you need to enter the radio device-specific security code. 在一种方案中,该无线电设备内设置一个电路,当断开电池时其使该无线电设备不能工作。 In one embodiment, a radio device disposed within the circuit, when its battery is disconnected so that the radio equipment is not working. 从而,为了再次使该无线电设备工作需要输入唯一的安全代码。 Accordingly, in order once again to make the work of radio equipment only need to enter the security code. 一种提供该安全代码的方法是把它存储在小型IS0/IEC 7816卡上并且在该无线电设备上设置一个其中可插入该卡的卡槽。 A method of providing the security code method is to store it in a small IS0 / IEC 7816 and set up a card which can be inserted into the card slot on the radio. 在该无线电设备中安装从该卡中读出代码的电路,该电路把该代码和该特定无线电设备的唯一代码进行比较,如果这二个代码匹配,则在再次连接电池后再次使该无线电设备能够运行。 In the radio equipment installed in the card is read out from the code circuit which the unique code of the code and the particular radio device are compared and if these two codes match, then again after connecting the battery again so that the radio equipment able to run.

发明内容 SUMMARY

[0007] 主电子系统的单个卡插座可以和一个或者多个遵照现有的一二种或更多种不同卡标准的可移动的插入卡交互作用,其中这些不同的卡标准由于卡的物理形状、外部接点的排列以及电信号接口的不同而彼此不兼容。 Single card socket [0007] the main electronic system and one or more may be in accordance with the existing twelve kinds or more different card standard removable plug-in card interactions among these different card standard due to the physical shape of the card different external contact arrangement and electrical interface and are not compatible with each other. 例如,一些数据,如唯一安全代码可以由遵照最适用于处理这种数据的IS0/IEC 7816的系统读出,而其它数据,如用户数据或操作程序可以由遵照为此目的设计的MMC或SD卡标准的系统读出。 For example, some data, such as a unique security code may be made in accordance with the most suitable for processing such data IS0 / IEC 7816 readout systems, and other data, such as user data or procedures may be designed for this purpose in accordance with the MMC or SD card standard system read out. 但是,本发明不受使用任何特殊的卡标准或者遵照现有卡标准存储的数据类型的限制。 However, the present invention is not to use any special card standard or follow the existing standard storage card data type restrictions.

[0008]在一具体实施例中,一种类型的卡的物理标准改变成和另一种类型的卡的物理标准一致,并且接着把每种类型的卡分别形成在一个具有其他类型卡的物理特征的组件中。 [0008] In one embodiment, the physical standards of one type of card and change into another type of physical standards consistent card, and then put each type of card are formed in a card having other types of physical feature component. 例如,把遵照IS0/IEC 7816标准的卡在物理上改变成具有由相关的MMC或SD卡标准所规定的相同的形状以及相同的引脚位置,使该电子系统的插座符合该卡标准。 For example, to comply with IS0 / IEC 7816 standard card has physically changed by the relevant standard MMC or SD card under the same shape and the same pin position so that the electronic system of the card socket in line with standards. 从而该电子系统的单个插座可接受二种或更多种的卡。 The electronic system whereby a single socket acceptable two or more cards.

[0009]在另一具体实施例中,在具有二个或更多卡标准中之一的物理尺寸和电气接点位置的单个卡上组合遵照这些卡标准的功能。 [0009] In another particular embodiment, the card has to follow these standard features on a single combination of two or more cards in one card standard physical dimensions and electrical contact position. 例如,可以把遵照相关的MMC或SD卡标准的卡修改成包含着遵照ISO/1EC7816标准的卡的电路,并且二个或更多不同标准的电气功能共享一组共用的卡接点。 For example, to comply with the relevant MMC or SD card standard card modified to comprise a circuit card in accordance with ISO / 1EC7816 standards, and two or more different standard electrical functions share a common set of card contacts.

[0010]这些实施例有许多应用。 [0010] These embodiments have many applications. 例如,在车辆无线电设备中,一个卡插座适应于接受含有安全代码的卡和接受含有音乐数据的存储器卡,当通过正确的安全代码启动后可以通过该车辆的音频系统再现该音乐。 For example, in a vehicle radio device, a card socket adapted to receive cards containing security codes and receive a memory card containing music data, when through the correct security code to start the music can be reproduced through the vehicle's audio system. 在另一个例子中,便携式电子设备,例如手持计算机、个人组织器、蜂窝电话等,具有一个卡插槽,该卡插槽接受含有应用程序的不时改变的一部分的卡或者含有供一应用程序使用的数据的卡,此外该卡插槽还接受一块含有能使该设备中的该应用程序操作的安全代码的卡。 In another example, the portable electronic devices, such as handheld computers, personal organizers, cellular phones, etc., with a card slot, the card slot accepts cards containing part of the application for change from time to time contain or use an application data card, in addition to the card slot also accepts one enables the device containing the application operation security code card. 在另一个例子中,GPS接收器卡插槽接受一块含有用户安全代码的卡以便启动该接收器的操作,以及接受含有该接收器操作中使用的数据的卡,以便确定位置等等。 In another example, GPS receivers card slot accepts a card containing user security code to start the operation of the receiver, and the receiver accepts the card containing the data used in the operation, in order to determine the position and so on. 在每种情况中,可以在同一卡上交替地含有应用数据和安全代码。 In each case, it may be alternately contain application data and security code on the same card.

[0011 ]在这些应用中,当使用独立的卡时,可以把安全代码存储在一块容量低且相对便宜的存储器卡上,该设备的拥有人通常应在一个可靠场所与该电子设备分开地保存该卡。 In these applications, when using a separate card, you can put on a low capacity and relatively inexpensive memory card, the owner of the equipment should normally be separately stored [0011] security code is stored in a secure place and the electronic device the card. 然后使用类型相同但存储量更大的一块或多块不同的存储器卡存储相关联的数据。 But then use the same type of one or more memory block of the memory card to store various data associated. 该电子设备内的电路在读插在槽中的卡时区分安全代码和关联数据并且相应地使用该数据。 The circuit of the electronic device at the time of reading the card inserted in the slot and the associated security code to distinguish between data and the corresponding use of the data.
